The arrest of al-Qaeda leader Mamdouh Mahmud Salim (a.k.a. Abu Hajer) points US and German investigators to Mohammed Haydar Zammar, a member of the al-Qaeda cell in Hamburg, Germany, with a few of the future 9/11 hijackers. Salim is arrested on September 16, 1998, in Munich, Germany (see September 16, 1998). He is believed to be al-Qaeda’s financial chief, and is one of al-Qaeda’s founding members (see August 11-20, 1988). After Salim’s arrest, both German and US intelligence investigate his contacts in Germany and discover a link to Zammar. Zammar is already being investigated and monitored by the Office for the Protection of the Constitution (BfV), Germany’s domestic intelligence service (see March 1997-Early 2000). [Der Spiegel (Hamburg), 12/12/2005] Presumably, the link between Zammar and Salim should increase the urgency of the German investigation. It is unknown when US intelligence begins monitoring Zammar, but the US will discover important links between Zammar and al-Qaeda in the summer of 1999 (see Summer 1999). US and German investigators also discover a link between Salim and Mamoun Darkazanli, a Hamburg associate of Zammar’s, and they monitor him as well (see Late 1998).

In the summer of 1999, the CIA asks border-control agencies in the Middle East to question anyone who may be returning from a training camp in Afghanistan, according to a 2004 Vanity Fair article. This is said to occur about six months before future 9/11 hijacker Ziad Jarrah is stopped and questioned at the airport in Dubai, United Arab Emirates, either because he is on a US watch list or because he shows signs of having come from Afghanistan, or both (see January 30, 2000 and December 14, 2001-September 28, 2005). [Vanity Fair, 11/2004] Also in 1999, the CIA specifically works out an arrangement with immigration officials at the Dubai airport to monitor or question suspected militants passing through (see 1999).

On December 5, 1999, a Jordanian raid discovers 71 vats of bomb making chemicals in this residence.On December 5, 1999, a Jordanian raid discovers 71 vats of bomb making chemicals in this residence. [Source: Judith Miller]Jordanian officials successfully uncover an al-Qaeda plot to blow up the Radisson Hotel in Amman, Jordan, and other sites on January 1, 2000. [PBS Frontline, 10/3/2002] The Jordanian government intercepts a call between al-Qaeda leader Abu Zubaida and a suspected Jordanian terrorist named Abu Hoshar. Zubaida says, “The training is over.” [New York Times, 1/15/2001] Zubaida also says, “The grooms are ready for the big wedding.” [Seattle Times, 6/23/2002] This call reflects an extremely poor code system, because the FBI had already determined in the wake of the 1998 US embassy bombings that “wedding” was the al-Qaeda code word for bomb. [Miller, Stone, and Mitchell, 2002, pp. 214] Furthermore, it appears al-Qaeda fails to later change the system, because the code-name for the 9/11 attack is also “The Big Wedding.” [Chicago Tribune, 9/5/2002] Jordan arrests Hoshar while he’s still on the phone talking to Zubaida. In the next few days, 27 other suspects are charged. A Jordanian military court will initially convict 22 of them for participating in planned attacks, sentencing six of them to death, although there will be numerous appeals (see April 2000 and After). In addition to bombing the Radisson Hotel around the start of the millennium, the plan calls for suicide bombings on two border crossings with Israel and a Christian baptism site. Further attacks in Jordan are planned for later. The plotters had already stockpiled the equivalent of 16 tons of TNT, enough to flatten “entire neighborhoods.” [New York Times, 1/15/2001] Key alleged plotters include:
bullet Raed Hijazi, a US citizen who is part of a Boston al-Qaeda cell (see June 1995-Early 1999). He will be arrested and convicted in late 2000 (see September 2000 and October 2000). [New York Times, 1/15/2001]
bullet Khalid Deek, who is also a US citizen and part of an Anaheim, California al-Qaeda cell. He will be arrested in Pakistan and deported to Jordan, but strangely he will released without going to trial.
bullet Abu Musab al-Zarqawi. He will later be a notorious figure in the Iraq war starting in 2003. [Washington Post, 10/3/2004]
bullet Luai Sakra. The Washington Post will later say he “played a role” in the plot, though he is never charged for it. Sakra apparently is a CIA informant before 9/11, perhaps starting in 2000 (see 2000). [Washington Post, 2/20/2006]
The Jordanian government will also later claim that the Al Taqwa Bank in Switzerland helped finance the network of operatives who planned the attack. The bank will be shut down shortly after 9/11 (see November 7, 2001). [Newsweek, 4/12/2004]

The CIA’s Counter Terrorism Center concludes in a classified report that bin Laden wants to inflict maximum casualties, cause massive panic, and score a psychological victory. He may be seeking to attack between five and 15 targets on the Millennium. “Because the US is bin Laden’s ultimate goal… we must assume that several of these targets will be in the US.” [Time, 8/12/2002; US Congress, 7/24/2003] CIA Director George Tenet delivers this warning to President Clinton. Author Steve Coll later comments that Tenet also “grabbed the National Security Council’s attention with that prediction.” [Coll, 2004, pp. 482] The US takes action in a variety of ways (see Early December 1999). It will turn out that bin Laden did plan many attacks to be timed for the millennium celebrations, including ones inside the US, but all failed (see December 31, 1999-January 1, 2000).

Ziad Jarrah, in an undated family photo taken in Lebanon.Ziad Jarrah, in an undated family photo taken in Lebanon. [Source: Getty Images]The UAE wants to arrest future 9/11 hijacker Ziad Jarrah, but US officials say they will track him instead, according to United Arab Emirates (UAE) officials. It is unknown if the US officials actually do so. On January 30, 2000, Jarrah is stopped and questioned as he is transiting through the airport in Dubai, UAE. Officials at the airport have agreed to help the CIA by monitoring or questioning suspicious militants passing through there (see 1999).
Conflicting Accounts - There will be some controversy about what happens next. According to a January 2002 FBI memo, “UAE authorities stopped Jarrah, apparently, because he had the Koran superimposed on part of his passport and he was carrying other religious materials.” [Chicago Tribune, 2/24/2004] But according to UAE officials, Jarrah is stopped because he is on a US watch list (see January 30, 2000).
Jarrah's Admissions - Regardless of why he is stopped, Jarrah is questioned and he all but admits he has just been to training camps in Afghanistan. A UAE official will later say, “When we questioned him, he said he spent two months and five days in Pakistan, some part of it in Afghanistan.” Furthermore, Jarrah says that he is going to the US to preach Islam and learn to fly airplanes.
UAE Officials Want to Arrest Him, but US Says No - While Jarrah is being held at the airport, UAE officials contact US officials and ask what they should do with him. (Note that there is some controversy about this as well, but FBI and German documents indicate the US is contacted while Jarrah is still being held (see January 30, 2000).) A UAE official will later say: “What happened was we called the Americans. We said: ‘We have this guy. What should we do with him?‘… [T]heir answer was, ‘Let him go, we’ll track him.’ We were going to make him stay. They told us to let him go. We weren’t feeling very happy in letting him go.” [Chicago Tribune, 2/24/2004; McDermott, 2005, pp. 186-187, 294-295] According to another account, UAE officials have a discussion with officials at the US embassy in Dubai on what to do with Jarrah. After some discussion, they conclude they do not actually have any charge to arrest him with, so it is decided to let him go. [Chicago Tribune, 9/28/2005]
UAE Officials Track Him to Hamburg; They Notify US Intelligence - After several hours of questioning, Jarrah is let go. He is allowed to board a flight for Amsterdam, Netherlands, but the flight does not leave until the next day, giving officials more time to prepare to track him if they want to. UAE officials are aware that after Jarrah arrives in Amsterdam, he changes planes for Hamburg, Germany. A UAE official will later say, “Where he went from there, we don’t know.” In fact, Jarrah lives in Hamburg and is part of the al-Qaeda cell there with fellow 9/11 hijacker Mohamed Atta and others. According to the FBI memo, this information about Jarrah’s detention and questioning “was reported to the US government.” UAE officials are cautious about mentioning which part of the US government is informed, but the implication is that it is the CIA. [Associated Press, 12/14/2001; Chicago Tribune, 2/24/2004; McDermott, 2005, pp. 186-187] However, it is unknown if US intelligence does track Jarrah.

The CIA and United Arab Emirates (UAE) officials apparently fail to warn German intelligence about future 9/11 hijacker Ziad Jarrah. On January 30, 2000, Jarrah was questioned at Dubai airport in the UAE, and the CIA was involved in a decision to not arrest him (see January 30-31, 2000). But even though Jarrah’s flight from Dubai was tracked to Hamburg, Germany, apparently neither US nor UAE officials warn German intelligence about Jarrah. During Jarrah’s brief detention he confessed that he had just come from Pakistan and Afghanistan, and he had a large number of jihadist propaganda videos in his luggage, leading UAE officials to strongly suspect he had just been to a militant training camp in Afghanistan. He also revealed that he has plans to learn how to fly airplanes in the US. An unnamed top German intelligence official will later say: “If we had been given the information that Jarrah had been to Afghanistan and was planning to go to flight school, we might have asked the Americans whether they thought this was normal.… If they had asked us, ‘Who is this guy who is learning to fly?’ then perhaps there might have been a different outcome.” He will suggest German intelligence might have started monitoring Jarrah, and thus discovered the 9/11 plot. However, this official will complain: “But it was one-way traffic [with the CIA]. You gave information, and you got no response.” The CIA will later deny that it has any knowledge of Jarrah before 9/11. [Vanity Fair, 11/2004] Note that a UAE official claims that the CIA said it would secretly track Jarrah from Dubai airport (see January 30-31, 2000). If this is true, it could explain why neither the UAE nor CIA told Germany about Jarrah.

Counterterrorism “tsar” Richard Clarke leads a meeting of the interagency Counterterrorism Security Group (CSG) devoted largely to the possibility of an airline hijacking by al-Qaeda. The meeting is said to come during a period of low threat, after the millennium alerts had ended (see December 15-31, 1999). Clarke later will recall that the possibility of a suicide hijacking would have been only one of many speculative possibilities considered. The apparent suicide hijacking of EgyptAir Flight 990 off the coast of Massachusetts in late 1999 appears to have been a concern of the CSG around this time (see October 31, 1999). Also, one month earlier, a militant group connected to al-Qaeda successfully hijacked an airplane in India, won their demands, and escaped (see December 24-31, 1999).

[Source: Fox News] (click image to enlarge)After the al-Qaeda summit in Kuala Lumpur, Malaysia, in January 2000 (see January 5-8, 2000), the CIA has Malaysian intelligence stop monitoring the condominium where the summit was held. The condominium is owned by al-Qaeda operative Yazid Sufaat, who plays a key role in al-Qaeda search for biological weapons (see December 19, 2001). According to a later Newsweek account, after the summit, “Malaysian intelligence continued to watch the condo at the CIA’s request, but after a while the agency lost interest.” It is unclear when the surveillance stops exactly, but it stops some time before al-Qaeda operative Zacarias Moussaoui visits Malaysia in September 2000. Moussaoui stays in Sufaat’s condominium, but the CIA misses a chance to learn about this (see September-October 2000). The Malaysians will later say they were surprised by the CIA’s lack of interest. “We couldn’t fathom it, really,” Rais Yatim, Malaysia’s Legal Affairs minister, will tell Newsweek. “There was no show of concern.” [Newsweek, 6/2/2002]

National Security Adviser Sandy Berger chairs a Cabinet-level meeting to review the wave of attempted terror attacks around the millennium. There are counterterrorism reports that disruption efforts “have not put too much of a dent” into bin Laden’s overseas network, and that it is feared “sleeper cells” of al-Qaeda operatives have taken root in the US. It is recommended that the FBI and the Immigration and Naturalization Service should begin “high tempo, ongoing operations to arrest, detain, and deport potential sleeper cells in the United States.” Some ideas, like expanding the number of Joint Terrorism Task Forces across the US, are adopted. Others, like a centralized translation unit for domestic intercepts, are not. [9/11 Commission, 3/24/2004] In July 2004, it is revealed that the Justice Department is investigating Berger for taking classified documents relating to this review effort out of a secure reading room in 2003. Most of the documents are returned, but a few apparently are lost. [Associated Press, 7/20/2004; Washington Post, 7/22/2004]

Drawings made by FBI sketch artists of Niaz Khan’s al-Qaeda contact in the US (left), and one of the people he trained with in Pakistan (right). [Source: NBC News]British intelligence fails to take advantage of an informant who may help penetrate al-Qaeda in the US, and even possibly the 9/11 plot. Niaz Khan, a British citizen originally from Pakistan, was recruited into an al-Qaeda plot to hijack an airplane in the US and possibly fly it into a building. It is unknown if this was the 9/11 plot or something else, because Khan became scared and never met his al-Qaeda contact in the US, and instead turned himself in to the FBI in April 2000. Khan said he trained in Pakistan for the hijacking. FBI agents checked out Khan’s story and gave him two lie detector tests, and after three weeks, they concluded he was telling the truth. But FBI headquarters was not interested and told the agents to get rid of him (see April 2000). Khan told the FBI he was ready to become an informant. His idea was to create a story to explain his failure to meet with his contact and then work undercover with Islamic radicals. Since the FBI wanted to get rid of him, it made arrangements with MI5, Britain’s domestic intelligence agency, so MI5 could handle him as an informant. [Vanity Fair, 11/2004] Khan is a British citizen and he had been recruited into the hijacking plot after he joined a radical Islamist mosque in London, so the hope is he will be able to identify and inform on the people who brought him into the plot. [MSNBC, 6/3/2004] Khan is put on a plane and flown with an FBI agent to London, where he is met by two MI5 agents. But according to an FBI agent who handles Khan, in 2004, Khan will explain that he only has a short meeting with MI5. “And then they let me go. I got on to the tube [subway] back home here to Manor Park. Even after 9/11 happened, I never saw anyone. I got no phone calls, no letters, nothing.” The FBI agent will later say: “I just assumed that when Niaz was turned over the British authorities would have conducted a full investigation. What I would have done is re-inserted him into the community and worked him.… We know that didn’t happen. It’s a real shame.” [Vanity Fair, 11/2004]

The US intelligence community considers creating a strategic analysis about terrorism, but none is done before 9/11. The last National Intelligence Estimate (NIE) on terrorism was released in 1997 (see 1997). The 9/11 Commission will later say that assessments such as NIEs can “provoke widespread thought and debate [and ] have a major impact on their recipients, often in a wider circle of decision makers.” By late 2000, CIA Director George Tenet recognizes the lack of any recent strategic analysis about al-Qaeda or Islamic militancy in general. He appoints a senior manager, who briefs him in March 2001 about “creating a strategic assessment capability.” The CIA’s Counterterrorist Center (CTC) establishes a new strategic assessments branch in July 2001 and about ten analysts are slated to work for it. But it takes time to hire the new staff and the first head of this branch reports for work just one day before 9/11. [9/11 Commission, 7/24/2004, pp. 342-343] Not only is there no NIE or any other sweeping strategic assessment on al-Qaeda between 1997 and 9/11, but one still will not be completed five years after 9/11. Apparently the US military opposes such an assessment for fear it would reduce the military’s role in counterterrorism efforts (see September 12, 2006).

Elie Assaad. Elie Assaad. [Source: ABC News]Elie Assaad is working as an undercover operative for the FBI, and he is sent to infiltrate the Al Hijrah mosque in Miramar, outside of Miami, Florida. Future 9/11 hijacker Mohamed Atta, who lives nearby at the time, frequents the mosque with Adnan Shukrijumah (see 2000-2001). Several years after 9/11, the US will call Shukrijumah an important al-Qaeda operative and will put out a $5 million reward for him. Assaad will later claim, “There was something wrong with these guys.” The small mosque is run by Adnan’s father, Gulshair Shukrijumah, who previously worked as a translator for Sheikh Abdul-Rahman, the “Blind Sheikh,” who was convicted of a role in the 1993 World Trade Center bombing. Assaad is posing as a personal representative of Osama bin Laden under the name “Mohammed.” He will later claim that Adnan invites him to meet him at his home, but the FBI tells him to stay away, because Atta and his associates are suspicious and secretive. Instead, Assaad’s FBI handlers assign him to go after easier targets: two “wannabe terrorists” whose cases are easy to solve (see November 2000-Spring 2002). Both targets are eventually convicted and sent to prison. After 9/11, Assaad will continue to work as an undercover operative for the FBI, and his work will be praised in 2006 by Attorney General Alberto Gonzalez. But others will criticize the cases he is involved in as entrapment against mostly harmless targets. ABC News will report on Assaad’s story after he retires from government work in 2009. In response, the FBI will issue a statement, saying, “The claims made in the news report and the factual conclusions contained in the story are not supported by the evidence.” The FBI will not specify which claims or conclusions it is referring to, and much of the story is a critique of post-9/11 FBI undercover stings in general. Former counterterrorism “tsar” Richard Clarke, working as an ABC News consultant, will call the case “yet another example of the way the system broke down prior to 9/11. If the system had worked, we might have been able to identify these people before the attacks.” [ABC News, 9/10/2009] It appears that the FBI is interested in Adnan Shukrijumah in two different cases around this time, but is unable to get close to him (see (Spring 2001)). In one case, an involved informant is known as “Mohamed,” which may well be Assaad using his alias “Mohammed.” A story on that case will suggest that Shukrijumah had a strong suspicion that “Mohamed” was a government informant (see April-May 2001).

Christopher Combs.Christopher Combs. [Source: Harvard Kennedy School]The FBI’s Washington, DC, field office (WFO) starts sponsoring training with fire department and law enforcement commanders in the Washington area on how emergency response workers and the FBI should coordinate their activities if there is a terrorist attack in the region. [Griffin, 3/30/2010, pp. 76 pdf file]
FBI Has Developed Relationships with Fire Departments - The WFO has already established relationships with fire chiefs in the Washington area, on the initiative of Special Agent Christopher Combs. [US Department of Health and Human Services, 7/2002, pp. 10 pdf file; Arlington TV, 10/8/2014] Combs is the assistant weapons of mass destruction (WMD) coordinator on the National Capital Response Squad (NCRS)—an antiterrorism rapid response unit—out of the WFO. [Goldberg et al., 2007, pp. 76; Federal Bureau of Investigation, 5/17/2011] When he was assigned to the NCRS in 1998, he realized that if there was a major emergency or a terrorist attack, the agency that would be doing rescues, tackling fires, and going into any wrecked buildings would be the fire department. He told his bosses: “If there was a major bombing today, the fire chief is going to own that scene. He needs a relationship with the FBI.” Combs was consequently allowed to begin a liaison program with the local fire departments. As the WFO’s fire service liaison, he then got to know fire department officials in Washington, Maryland, and Virginia; set up joint training programs; and made sure the FBI understood fire department procedures. He also taught courses at the area’s fire academies on terrorism, WMDs, and the responsibilities of the FBI. [US Department of Health and Human Services, 7/2002, pp. A47 pdf file; Creed and Newman, 2008, pp. 8]
FBI Sponsors Training with Fire and Law Enforcement Departments - The WFO now expands its regional outreach activities by starting to sponsor training with the fire and law enforcement command staffs in the Washington area. This training will introduce FBI officials to local first responders. It will allow these officials to share lessons learned from the Oklahoma City bombing in 1995 (see 8:35 a.m. - 9:02 a.m. April 19, 1995), and present “conceptual operational theories” of how the FBI and first responders could coordinate their actions during a terrorist attack.
Outreach Efforts Improve the Response to the Pentagon Attack - Combs’s outreach efforts with emergency response agencies in the Washington area will reportedly pay dividends when these agencies have to respond to the attack on the Pentagon on September 11. [US Department of Health and Human Services, 7/2002, pp. A47 pdf file; Kettl, 2008, pp. 203-204; Griffin, 3/30/2010, pp. 76-77 pdf file] Emergency responders and the FBI will have “been through numerous exercises together so that at the Pentagon we all knew each other and the capabilities of each agency,” Combs will later say. “We knew the roles and responsibilities, so we already knew who was in charge and what phase we were in,” he will add.

A confidential informant tells an FBI field office agent that he has been invited to a commando-training course at a training camp operated by al-Qaeda in Afghanistan. The information is passed up to FBI headquarters, which rejects the idea of infiltrating the camp. An “asset validation” of the informant, a routine but critical exercise to determine whether information from the source was reliable, is also not done. The FBI later has no comment on the story. [US News and World Report, 6/10/2002] Around this time, John Walker Lindh, a Caucasian US citizen who recently converted to Islam, goes to one of the training camps for the first time and learns details of the 9/11 in a matter of weeks (see May-June 2001). Also around this time, seven men from Lackawanna, New York, go to a training camp in Afghanistan and hear clues about the 9/11 attacks before they drop out after only a few weeks (see (June 2001)).

Army General Tommy Franks raises concerns that al-Qaeda will attack Western facilities in the Middle East using planes loaded with explosives. [Franks, 2004, pp. 235-236; Globe and Mail, 10/9/2004] As commander in chief of the US Central Command (CENTCOM), Franks is in charge of US military operations in an area covering 25 nations in North Africa, Central Asia, and the Middle East. [CNN, 10/24/2001; ABC News, 1/7/2006] “Through the spring of 2001 and into the summer, protecting our deployed troops from terrorists remained an ever-present concern,” he will later write. During the summer, CENTCOM intelligence officers work with the CIA and the Defense Intelligence Agency, “collecting and analyzing persistent but unspecific indications of planned terrorist activity in the Middle East.” On several occasions, Franks increases CENTCOM’s force protection posture—the “Threatcon”—“but never as a result of a specific threat” (see June 21, 2001). “Something was brewing, but the best minds at the CIA and the National Security Agency could not pin down the threats with any degree of certainty,” he will comment. “Where would we see a terrorist act… and when?” As he reads “the increasingly alarming reports of potential attacks on Western facilities in the region,” it occurs to Franks that al-Qaeda might carry out suicide attacks using aircraft. “Al-Qaeda had used cars, trucks, and boats as suicide bombs,” he will write. “What about small planes loaded with high explosives?” He sends a note—first to the US embassy in Riyadh, Saudi Arabia, and then to the other US embassies within CENTCOM’s area of responsibility—in which he asks the ambassadors to pass on his concerns to their hosts. He tells them, “We should work to tune the host nations in the region in to this type of threat.” [Franks, 2004, pp. 235-236]

Mohammed Haydar Zammar, a member of the al-Qaeda cell in Hamburg, Germany, is detained in Jordan and then let go. According to a German intelligence official speaking in 2002, Zammar is in transit through Jordan. However, the official will not say where Zammar is going, where he is coming from, or why he is held. Zammar is detained for several days and then deported back to Germany. [Washington Post, 6/12/2002] When Zammar is questioned by German intelligence shortly after 9/11 (see Shortly After September 11-October 27, 2001), he will mention his detention in Jordan. He will say that Jordanian officials “asked me about Afghanistan, the people there, my beliefs, contacts in Jordan, and my party membership. By party membership that meant whether I was a follower of Hezbollah, Hamas, [Islamic] Jihad, or Osama bin Laden.” [New York Times, 1/18/2003] Interestingly, in the beginning of July, CIA Director George Tenet made an urgent request to allied intelligence agencies to arrest anyone on a list of known al-Qaeda operatives (see July 3, 2001). In 1999, US intelligence determined that Zammar was in contact with one of Osama bin Laden’s senior operational coordinators, and the US notes Zammar’s terrorist links on numerous occasions before 9/11 (see Summer 1999), so Zammar would be a likely candidate for Tenet’s list. Zammar also was the target of a German intelligence investigation that started in 1996 and lasted at least three years (see 1996).

According to statements by FBI whistleblower Sibel Edmonds in 2004 and 2005, in July or August 2001, an unnamed FBI field agent discovers foreign documentation revealing “certain information regarding blueprints, pictures, and building material for skyscrapers being sent overseas. It also reveal[s] certain illegal activities in obtaining visas from certain embassies in the Middle East, through network contacts and bribery.” The document is in a foreign language and apparently the agent isn’t given an adequate translation of it before 9/11. Approximately one month after 9/11, the agent will suspect the original translation is insufficient and will ask the FBI Washington Field Office to retranslate it. The significant information mentioned above will finally be revealed, but FBI translation unit supervisor Mike Feghali will decide not to send this information back to the field agent. Instead, he will send a note stating that the translation was reviewed and the original translation was accurate. The field agent will never receive the accurate translation. This is all according to Edmonds’s letter. Edmonds will claim Feghali “has participated in certain criminal activities and security breaches, and [engaged] in covering up failures and criminal conducts within the department.” While the mainstream media will not report on this incident, in January 2005 an internal government report will determine that most of Edmonds’s allegations have been verified and none of them could be refuted.

The FBI’s Counterterrorism Division issues a warning of possible al-Qaeda attacks to law enforcement agencies called “Potential Anti-US Attacks.” It states: “[T]here are threats to be worried about overseas. While we cannot foresee attacks domestically, we cannot rule them out.” It further states, “[T]he FBI has no information indicating a credible threat of terrorist attack in the United States.” It asks law enforcement agencies to “exercise vigilance” and “report suspicious activities” to the FBI. Two weeks later, acting FBI Director Thomas Pickard has a conference call with all field office heads mentioning the heightened threat (see July 19, 2001). However, FBI personnel later fail to recall any heightened sense of threat from summer 2001. Only those in the New York field office take any action or will recall this later.

The American Hospital in Dubai.The American Hospital in Dubai. [Source: American Hospital]Bin Laden, America’s most wanted criminal with a $5 million bounty on his head, supposedly receives lifesaving treatment for renal failure from American specialist Dr. Terry Callaway at the American hospital in Dubai, United Arab Emirates. He is possibly accompanied by Dr. Ayman al-Zawahiri (who is said to be bin Laden’s personal physician as well as al-Qaeda’s second-in-command), plus several bodyguards. Callaway supposedly treated bin Laden in 1996 and 1998, also in Dubai. Callaway later refuses to answer any questions on this matter. [Le Figaro (Paris), 10/31/2001; Agence France-Presse, 11/1/2001; London Times, 11/1/2001] During his stay, bin Laden is visited by “several members of his family and Saudi personalities,” including Prince Turki al-Faisal, then head of Saudi intelligence. [Guardian, 11/1/2001] On July 12, bin Laden reportedly meets with CIA agent Larry Mitchell in the hospital. Mitchell apparently lives in Dubai as an Arab specialist under the cover of being a consular agent. The CIA, the Dubai hospital, and even bin Laden deny the story. The two news organizations that broke the story, Le Figaro and Radio France International, stand by their reporting. [Le Figaro (Paris), 10/31/2001; Radio France International, 11/1/2001] The explosive story is widely reported in Europe, but there are only two, small wire service stories on it in the US. [United Press International, 11/1/2001; Reuters, 11/10/2001] The Guardian claims that the story originated from French intelligence, “which is keen to reveal the ambiguous role of the CIA, and to restrain Washington from extending the war to Iraq and elsewhere.” The Guardian adds that during his stay bin Laden is also visited by a second CIA officer. [Guardian, 11/1/2001] In 2003, reporter Richard Labeviere will provide additional details of what he claims happened in a book entitled “The Corridors of Terror.” He claims he learned about the meeting from a contact in the Dubai hospital. He claims the event was confirmed in detail by a Gulf prince who presented himself as an adviser to the Emir of Bahrain. This prince claimed the meeting was arranged by Prince Turki al-Faisal. The prince said, “By organizing this meeting…Turki thought he could start direct negotiations between [bin Laden] and the CIA on one fundamental point: that bin Laden and his supporters end their hostilities against American interests.” In exchange, the CIA and Saudis would allow bin Laden to return to Saudi Arabia and live freely there. The meeting is said to be a failure. [Reuters, 11/14/2003] On July 15, Larry Mitchell reportedly returns to CIA headquarters to report on his meeting with bin Laden. [Radio France International, 11/1/2001] French counterterrorism expert Antoine Sfeir says the story of this meeting has been verified and is not surprising: It “is nothing extraordinary. Bin Laden maintained contacts with the CIA up to 1998. These contacts have not ceased since bin Laden settled in Afghanistan. Up to the last moment, CIA agents hoped that bin Laden would return to the fold of the US, as was the case before 1989.” [Le Figaro (Paris), 11/1/2001] A CIA spokesman calls the entire account of bin Laden’s stay at Dubai “sheer fantasy.” [Reuters, 11/14/2003]

On July 10, 2001, Phoenix FBI agent Ken Williams sends a memorandum to FBI headquarters urging a nationwide check on Middle Eastern students at flight schools (see July 10, 2001), but apparently neither Williams nor anyone else actually conducts any kind of check on Phoenix flight schools at this time. Phoenix flight school managers will later claim that the FBI does not ask them for tips on suspicious students before 9/11. A Sawyer School manager apparently had suspicions about some of his students (though he does not mention alleged Flight 77 pilot Hani Hanjour specifically). He later will say that had he known the FBI was concerned that some students might be Islamic militants, “I would have called someone.” Another flight school manager claims he has a good relationship with the FBI and is surprised he is not asked about Williams’s concerns. He will complain, “Should flight schools be clairvoyant?” [New York Times, 5/24/2002; 9/11 Commission, 7/24/2004, pp. 529] In fact, although Hanjour left Arizona in March 2001 and lived on the East Coast after that time, there is evidence he comes back for some flight training in the Phoenix area in June and August 2001, including at the Sawyer School (see Summer 2001). The 9/11 Commission will later note that the evidence of Hanjour training in Phoenix during the summer is not definitive, but “the FBI’s Phoenix office believes it is plausible that Hanjour return[s] to Arizona for additional training.” [New York Times, 5/24/2002; 9/11 Commission, 7/24/2004, pp. 529] It does not appear that Williams or any other FBI official checks flight schools anywhere else in Arizona before 9/11.

Al-Qaeda operative Luai Sakra is reportedly arrested by Turkish intelligence in Turkey and then let go. It will later appear that Sakra was an informant for the CIA, Turkish intelligence, and Syrian intelligence before 9/11. He appears to have begun working for the CIA and Turkish intelligence in 2000 (see 2000). Sakra will later claim to have been arrested and quickly released twice by Turkish intelligence. It seems the first time was in 2000 and this was the second time. [Der Spiegel (Hamburg), 8/24/2005] It would make sense that he was released at this time if he was a secret informant for Turkey. It will later come to light that Sakra had some foreknowledge of the 9/11 attacks and warned Syrian intelligence about them one day before the attacks (see September 10, 2001). But it is not known if he used this arrest to warn Turkish intelligence and/or the CIA as well.

George Tabeek.George Tabeek. [Source: Fairleigh Dickinson University]George Tabeek, a security manager with the Port Authority of New York and New Jersey, expresses his concerns about an aircraft crashing into the World Trade Center, perhaps in a terrorist attack. [CBS News, 2/11/2009; New Jersey Star-Ledger, 9/6/2011] The Port Authority was, until late July, responsible for the management and operation of the WTC (see July 24, 2001), and most Port Authority World Trade Department employees are still working in the WTC. [Port Authority of New York and New Jersey, 7/24/2001; IREIzine, 7/26/2001; 9/11 Commission, 7/24/2004, pp. 281]
Possibility of Plane Hitting WTC Discussed - Tabeek, the Port Authority’s security manager for the WTC since 1999, will later say that, following the 1993 bombing of the WTC (see February 26, 1993), the Port Authority “put thousands and thousands of hours into safety construction and safety procedures.” Over $100 million has been spent on improving security and fire safety. Therefore, according to Tabeek, “the World Trade Center was safer on 9/11 than 99 percent of the buildings in America.” Tabeek will say: “We were already looking into bio-chem. We were talking about weapons of mass destruction.” He will add that, just two weeks before 9/11, “[W]e talked about ever getting hit by a plane, but it was never in our wildest dreams a commercial airliner.” [FDU Magazine, 6/2008; CBS News, 2/11/2009]
Possibility of Attack Using Plane Discussed with New Head of Security - Tabeek discusses the possibility of a plane hitting the WTC again on September 6, the Thursday before 9/11. That evening, John O’Neill, the new head of security at the WTC (see August 23, 2001), calls him to a conference room in the South Tower, to discuss security and “threat assessment.” During the meeting, Tabeek describes the improved security at the WTC, telling O’Neill: “We’re 99 percent locked down. You’re not going to get in here with a bomb that’s going to do substantial damage within the building, because we minimized that.” According to Tabeek, O’Neill asks: “Okay, you say to me we’re 99 percent locked down. What’s the other 1 percent?” Tabeek replies, “A plane.” O’Neill says, “Come on, you’re grabbing at straws.” But Tabeek tells him, “No, in ‘93 we’re an American economic bad cop… and now we’re an American-Israeli economic bad cop, more of a threat today than we ever were.” He adds that the plane involved would be “a corporate jet slamming into the building,” with “minimal loss of life, minimal economic loss.” Tabeek will later comment, “I never expected something bigger.” [New Jersey Star-Ledger, 9/6/2011] An analysis carried out on behalf of the Port Authority after the 1993 WTC bombing identified the scenario of terrorists deliberately crashing a plane into the Twin Towers as one of a number of possible threats (see After February 26, 1993). [Jenkins and Edwards-Winslow, 9/2003, pp. 11] Tabeek will tell one magazine, “We had planned for the possibility of a small airplane—a corporate jet, maybe—crashing into one of the [WTC] buildings by accident.” [FDU Magazine, 6/2008]

CIA Director George Tenet will claim in his 2007 book that “a group of assets from a Middle Eastern service” is unknowingly working for the CIA by this time. Out of the more than twenty people in this group, one third are working against al-Qaeda. By September 2001, two assets have successfully penetrated al-Qaeda training camps in Afghanistan. [Tenet, 2007, pp. 145] The name of the Middle Eastern country is not known. It is also not known when this group first started working for the CIA nor when the assets first penetrated the camps. Nor has it been reported what information these assets may have shared with the CIA before 9/11. It is known that bin Laden was dropping hints about the upcoming 9/11 attacks to training camp trainees in the summer of 2001 (see Summer 2001). Further, US citizen John Walker Lindh was told details of the 9/11 attacks within weeks of joining a training camp that summer (see May-June 2001).
