Hendropriyono, the Indonesian chief of intelligence, will later claim that, “[we] had intelligence predicting the September 11 attacks three years before it happened but nobody believed us.” He says Indonesian intelligence agents identify bin Laden as the leader of the group plotting the attack and that the US disregards the warning, but otherwise offers no additional details. The Associated Press notes, “Indonesia’s intelligence services are not renowned for their accuracy.” [Associated Press, 7/9/2003]

German intelligence gives the CIA the first name of 9/11 hijacker Marwan Alshehhi and his telephone number of a phone registered in the United Arab Emirates (UAE). The Germans learned the information from the surveillance of al-Qaeda Hamburg cell member Mohammed Haydar Zammar (see March 1997-Early 2000). They tell the CIA that Alshehhi, who is living in Bonn, Germany, at the time, may be connected to al-Qaeda. He is described as a UAE student who has spent some time studying in Germany. The conversation is short, but a known alias of Mamoun Darkazanli is mentioned. The CIA is very interested in Darkazanli and will try to recruit him as an informant later in the year (see Late 1998 and December 1999). [US Congress, 7/24/2003 pdf file; Deutsche Presse-Agentur (Hamburg), 8/13/2003; New York Times, 2/24/2004; McDermott, 2005, pp. 73, 278-279]
No Response from CIA - The Germans consider this information “particularly valuable” and ask the CIA to track Alshehhi, but the CIA never responds until after the 9/11 attacks. The CIA decides at the time that this “Marwan” is probably an associate of bin Laden but never track him down. It is not clear why the CIA fails to act, or if they learn his last name before 9/11. [New York Times, 2/24/2004] The Germans monitor other calls between Alshehhi and Zammar, but it isn’t clear if the CIA is also told of these or not (see September 21, 1999).
Could the Number Be Traced? - CIA Director George Tenet will later dismiss the importance of this information in a statement to the 9/11 Congressional Inquiry. He will say that all the CIA had to go on was a first name and an impossible to trace unlisted number. But author Terry McDermott will later comment, “At least a portion of that statement is preposterous. The UAE mobile telephone business was, until 2004, a state monopoly. The UAE number could have been traced in five minutes, according to senior security officials there. The United States never asked.” McDermott will add, “Further, the CIA told the [9/11 Congressional Inquiry] it had a long-standing interest in Zammar that pre-dated these recordings. In other words, the CIA appears to have been investigating the man who recruited the hijackers at the time he was recruiting them.” [McDermott, 2005, pp. 73, 278-279]

MI5, Britain’s domestic intelligence agency, reports, “Intelligence suggests that while [Osama bin Laden] is seeking to launch an attack inside the US, he is aware that the US will provide a tough operating environment for his organization.” [Daily Telegraph, 10/5/2009] It is unclear who this report is sent to, or what information it is based on. MI6, not MI5, is usually tasked with foreign intelligence.

Abdulsalam Ali Abdulrahman.Abdulsalam Ali Abdulrahman. [Source: US Defense Department]Italian intelligence successfully wiretaps an al-Qaeda cell in Milan, Italy, starting in late 1999. [Boston Globe, 8/4/2002] In a wiretapped conversation from this day, Abdulsalam Ali Abdulrahman, a section chief in Yemen’s Political Security Organization (PSO - roughly the equivalent to the FBI in the US) traveling on a diplomatic passport (see Spring-Summer 1998), talks about a massive strike against the enemies of Islam involving aircraft and the sky. The conversation takes place in a car on the way to a terrorist summit near Bologna (see August 12, 2000 and Shortly After), and the person Abdulrahman talks to is Mahmoud Es Sayed, a close associate of al-Qaeda second-in-command Ayman al-Zawahiri (see Before Spring 2000). There are several significant aspects to the conversation:
bullet Abdulrahman makes comments indicating he has foreknowledge of the 9/11 attacks. He says that he is “studying airlines,” comments, “Our focus is only on the air,” and tells Es Sayed to remember the words “above the head.” He also says that next time they meet he hopes to bring Es Sayed “a window or piece of the airplane,” and that the security on Alitalia and at Rome airport is poor. The name of the operation is given as “Jihadia,” and Abdulrahman says, “the big blow will come from the other country: one of those blows no one can ever forget.” He adds: “[It is] moving from south to north, from east to west: whoever created this plan is crazy, but he’s also a genius. It will leave them speechless.” He also says: “We can fight any power using candles and airplanes: they will not be able to stop us with even their most powerful weapons. We must hit them. And keep your head up.… Remember, the danger in the airports.… If it happens the newspapers from all over the world will write about it.”
bullet Es Sayed remarks, “I know brothers who went to America with the trick of the wedding publications.” The phrase “Big wedding” is sometimes used by al-Qaeda as code for a bombing or attack, including 9/11 (see November 30, 1999 and Late Summer 2001), so, taken together with Abdulrahman’s remarks, this indicates an unconventional attack in the US using aircraft;
bullet The two discuss training camps in Yemen, which are “proceeding on a world scale.” They also mention youth in Italy, and presumably the youth are training;
bullet Es Sayed says, “my dream is building an Islamic state,” and Abdulrahman replies that this is possible because the Yemeni government is weak and “sooner or later we will dominate it;”
bullet Es Sayed asks after a person named Ayman, evidently al-Qaeda second-in-command Ayman al-Zawahiri;
bullet Abdulrahman twice mentions the name of Abdul Mejid, apparently a reference to Abdul Mejid al-Zindani, a radical leader in Yemen and associate of Osama bin Laden (see January-August 1998);
bullet Es Sayed makes the cryptic comment, “One must be cautious, like in Iran; not a single photo.”
Beginning in October 2000, FBI experts will help Italian police analyze the intercepts and warnings. Related conversations are overheard early the next year (see January 24, 2001 and February 2001). Neither Italy nor the FBI will fully understand their meaning until after 9/11, but apparently the Italians will understand enough to give the US an attack warning in March 2001 (see March 2001). After 9/11, this conversation and others like it will cause US intelligence to think there may be a link between the 9/11 plot and Yemen’s PSO. [Los Angeles Times, 5/29/2002; Guardian, 5/30/2002; Washington Post, 5/31/2002; Wall Street Journal, 12/20/2002; Vidino, 2006, pp. 224-5] Author Lorenzo Vidino will later comment: “The chilling conversation alarmed officials before 9/11, but it took on a completely different resonance after the attacks had taken place. [Abdulrahman], who had close connections to the highest ranks of al-Qaeda, likely knew about the plan in advance and had told Es Sayed about it.” [Vidino, 2006, pp. 226]

Italian intelligence hears an interesting wiretapped conversation eerily similar to one from August 12, 2000 (see August 12, 2000). This conversation occurs between al-Qaeda operatives Mahmoud Es Sayed (see Summer 2000) and Ben Soltane Adel, two members of al-Qaeda’s Milan cell. Adel asks, in reference to fake documents, “Will these work for the brothers who are going to the United States?” Sayed responds angrily, saying: “[D]on’t ever say those words again, not even joking!… If it’s necessary… whatever place we may be, come up and talk in my ear, because these are very important things. You must know… that this plan is very, very secret, as if you were protecting the security of the state.” This will be one of many clues found from the Italian wiretaps and passed on to US intelligence in March 2001 (see March 2001). However, they apparently will not be properly understood until after 9/11. Adel will later be arrested and convicted of belonging to a terrorist cell, and Es Sayed will flee to Afghanistan in July 2001. [Los Angeles Times, 5/29/2002; Guardian, 5/30/2002]

The Italian government gives the US information about possible attacks based on apartment wiretaps in the Italian city of Milan. [Fox News, 5/17/2002] Presumably, the information includes a discussion between two al-Qaeda agents talking about a “very, very secret” plan to forge documents “for the brothers who are going to the United States” (see January 24, 2001). The warning may also mention a wiretap the previous August involving one of the same people, who discussed a massive strike against the enemies of Islam involving aircraft (see August 12, 2000) and another of his monitored conversations in which he discusses travel by al-Qaeda operatives to the US (see February 2001).

Word begins to spread within al-Qaeda that an attack against the US is imminent, according to later prison interrogations of Khalid Shaikh Mohammed. Many within al-Qaeda are aware that Mohammed has been preparing operatives to go to the US. Additionally, bin Laden makes several remarks hinting at an upcoming attack, spawning rumors throughout Muslim extremist circles worldwide.
bullet In a recorded speech at the Al Farooq training camp in Afghanistan, Osama bin Laden specifically urges trainees to pray for the success of an upcoming attack involving 20 martyrs. [9/11 Commission, 6/16/2004]
bullet Members of the “Lackawanna Six” see bin Laden give a recorded speech at the Al Farooq camp in which he urges trainees to pray for 40 en route on a very important mission. It is not known if this is the same as the other Al Farooq speech or a separate one (see (June 2001)).
bullet A bin Laden bodyguard later will claim that in May 2001 or earlier in the year he heard bin Laden tell people in Afghanistan that the US would be hit with an attack, and thousands would die (see Early 2001). [Guardian, 11/28/2002]
bullet In mid-June 2001, bin Laden tells training camp trainees there will be an attack in the near future. US intelligence soon learns of this (see Mid-June 2001).
bullet In June 2001, the CIA hears that Arabs in Afghanistan are said to be anticipating as many as eight celebrations, and al-Qaeda operatives are being told to await important news within days (see June 2001).
bullet John Walker Lindh learns details of the 9/11 attack despite being a Caucasian and US citizen who only recently converted to Islam (see May-June 2001).
There are other indications that knowledge of the attacks spreads in Afghanistan. The Daily Telegraph later reports that “the idea of an attack on a skyscraper [is] discussed among [bin Laden’s] supporters in Kabul.” At some unspecified point before 9/11, a neighbor in Kabul sees diagrams showing a skyscraper attack in a house known as a “nerve center” for al-Qaeda activity. [Daily Telegraph, 11/16/2001] US soldiers will later find forged visas, altered passports, listings of Florida flight schools and registration papers for a flight simulator in al-Qaeda houses in Afghanistan.

In 2002, the Washington Post will report, “European officials, including the German authorities, said that while they had indications in the summer of 2001 that al-Qaeda was planning a major attack, they had no specifics on what form it would take, where it would occur, or who, specifically, was involved.” [Washington Post, 6/12/2002] Other details will remain unknown, such as what other European countries besides Germany might know this. Also, it is unclear if this information is passed to the US. However, there will be other reports that in June 2001, German intelligence warns the CIA, Britain, and Israel that Middle Eastern militants are planning to hijack commercial aircraft to use as weapons to attack “American and Israeli symbols, which stand out” (see June 2001). British and French intelligence are also said to warn the US about a major al-Qaeda attack in the summer of 2001 (see July 6, 2001, July 16, 2001, Early August 2001, Late August 2001, and September 7, 2001).

The Associated Press will report in May 2002, “Israeli intelligence services were aware several months before Sept. 11 that bin Laden was planning a large-scale terror attack but did not know what his targets would be, Israeli officials have said. An Israeli official, speaking on condition of anonymity, tells the Associated Press shortly after the attacks that ‘everybody knew about a heightened alert and knew that bin Laden was preparing a big attack.’ He said information was passed on to Washington but denied Israel had any concrete intelligence that could have been used to prevent the Sept. 11 attacks.” [Associated Press, 5/19/2002] The claim that Israel lacks concrete intelligence is contradicted by other media reports (see August 8-15, 2001) (see August 23, 2001) (see September 4, 2001).

However, there were other informational sources, including specific information and hints given to, but not reported by, Western and Near Eastern news media six months before 9/11. [Frankfurter Allgemeine Zeitung (Frankfurt), 9/11/2001; Washington Post, 9/14/2001; Fox News, 5/17/2002] According to a separate account, in the summer of 2001, German officials are aware that al-Qaeda is planning a major attack, but they don’t know the details (see Summer 2001).

At some point in 2000, three men claiming to be Afghans but using Pakistani passports entered the Cayman Islands, possibly illegally. [Miami Herald, 9/20/2001] In late 2000, Cayman and British investigators began a yearlong probe of these men, which will last until 9/11. [Los Angeles Times, 9/20/2001] They are overheard discussing hijacking attacks in New York City during this period. On this day, they are taken into custody, questioned, and released some time later. This information is forwarded to US intelligence. [Fox News, 5/17/2002] In late August, a letter to a Cayman radio station will allege these same men are agents of bin Laden “organizing a major terrorist act against the US via an airline or airlines.” [Miami Herald, 9/20/2001; Los Angeles Times, 9/20/2001]

ABC News has learned Jordan told US officials al-Qaeda was planning an attack on American soil.” [ABC News, 2/19/2002] It has been reported elsewhere that in late summer 2001, Jordan warns the US that aircraft will be used in a major attack inside the US, but it is not known if that is a separate warning or the same as this one (see Late Summer 2001). Also in late July, Jordan will offer the US to send its elite troops to Afghanistan to attack al-Qaeda, an offer the US turns down (see July 24, 2001). Also in July 2001, Jordan briefly detains and interrogates Mohammed Haydar Zammar, a member of the Hamburg cell with three of the 9/11 hijackers (see July 2001). Zammar appears to have foreknowledge of the 9/11 plot around this time (see August 2001).

Sir Stephen Lander.Sir Stephen Lander. [Source: Public domain]According to an officially authorized book on the MI5 published in 2009, Britain’s domestic intelligence agency, MI5, warns top British leaders that a surge in the number of reports of threat information is “sufficient to conclude that [Osama bin Laden] and those that share his agenda are currently well advanced in operational planning for a number of major attacks on Western interests.” Similar MI5 warnings about an imminent attack will continue up until 9/11, including one put out on the morning of 9/11. However, apparently none of these suggest a major attack in the US or an attack using hijacked airplanes. MI6 is Britain’s foreign intelligence agency, and presumably most information about al-Qaeda and attack threats would come from it and not MI5. In fact, MI5 appears to be much less aware of al-Qaeda at this time. Sir Stephen Lander, director general of MI5 from 1996 to 2002, will later say that MI5 was “slow to get going” on the al-Qaeda threat because it was preoccupied with the IRA, and after 9/11 it had a “major set to, sitting around a board room table working out how to move on.” [Daily Telegraph, 10/5/2009] This warning appears similar, but not identical, to a warning 10 days later that is an analysis involving all British intelligence agencies (see July 16, 2001).

British intelligence agencies send a report to British Prime Minister Tony Blair and other top officials warning that al-Qaeda is in “the final stages” of preparing an attack in the West. The prediction is “based on intelligence gleaned not just from [British intelligence] but also from US agencies, including the CIA and the National Security Agency,” which cooperate with the British. “The contents of the July 16 warning would have been passed to the Americans, Whitehall sources confirmed.” The report states there is “an acute awareness” that the attack is “a very serious threat.” [London Times, 6/14/2002] This appears to be similar, but not identical, to a warning to British leaders from MI5, Britain’s domestic intelligence agency, 10 days earlier (see July 6, 2001).

CBS later reports, in a long story on another topic: “Just days after [Mohamed] Atta return[s] to the US from Spain, Egyptian intelligence in Cairo says it received a report from one of its operatives in Afghanistan that 20 al-Qaeda members had slipped into the US and four of them had received flight training on Cessnas. To the Egyptians, pilots of small planes didn’t sound terribly alarming, but they [pass] on the message to the CIA anyway, fully expecting Washington to request information. The request never [comes].” [CBS News, 10/9/2002] This appears to be just one of several accurate Egyptian warnings from their informants inside al-Qaeda. Around this time, word of the upcoming 9/11 attacks is spreading widely in the training camps in Afghanistan. For instance, in a recorded speech played at one of the camps, Osama bin Laden specifically urges trainees to pray for the success of an upcoming attack involving 20 martyrs (see Summer 2001).

Says a Jewish leader, “It was a concrete warning that an attack of major proportion would take place, and it came from a reliable intelligence source.

Taliban Foreign Minister Wakil Muttawakil.Taliban Foreign Minister Wakil Muttawakil. [Source: Reuters]Taliban Foreign Minister Wakil Ahmed Muttawakil learns that bin Laden is planning a “huge attack” on targets inside America. The attack is imminent, and will kill thousands. He learns this from Tahir Yuldashev, top leader of the rebel Islamic Movement of Uzbekistan (IMU), which is allied with al-Qaeda at the time. Yuldashev apparently is worried that a large al-Qaeda attack will lead to a US attack on Afghanistan, which would threaten the IMU’s safe haven there. Muttawakil sends an emissary to pass this information on to the US consul general, and another US official, “possibly from the intelligence services,” also attends the meeting. The message is not taken very seriously; one source blames this on “warning fatigue” from too many warnings. In addition, the emissary supposedly is from the Foreign Ministry, but did not say the message came from Muttawakil himself. The emissary then takes the message to the Kabul offices of UNSMA, the political wing of the UN. They also fail to take the warning seriously. [Independent, 9/7/2002; Reuters, 9/7/2002]

Jordanian intelligence (the GID) makes a communications intercept deemed so important that King Abdullah’s men relay it to Washington, probably through the CIA station in Amman. To make doubly sure the message gets through it is passed through an Arab intermediary to a German intelligence agent. The message states that a major attack, code named “The Big Wedding,” is planned inside the US and that aircraft will be used. “When it became clear that the information was embarrassing to Bush administration officials and congressmen who at first denied that there had been any such warnings before September 11, senior Jordanian officials backed away from their earlier confirmations.” The Christian Science Monitor will call the story “confidently authenticated” even though Jordan has backed away from it. [International Herald Tribune, 5/21/2002; Christian Science Monitor, 5/23/2002] It has been reported elsewhere that in July 2001, Jordan warns the US that al-Qaeda is planning an attack inside the US, but it is unknown if this is referring to the same warning or a separate one (see July 2001). In late July 2001, the king of Jordan will offer the US to send two battalions of Jordanian special forces to Afghanistan to eliminate al-Qaeda havens there (see July 24, 2001).

In 1999, a Moroccan named Hassan Dabou infiltrated al-Qaeda for the Moroccan intelligence agency. He was sent to Afghanistan, posing as an Islamic radical on the run from the Moroccan government. While there, he was able to grow close to bin Laden. He heard bin Laden repeatedly vent his anger at the failure of the World Trade Center bombing in 1993 (see February 26, 1993). Bin Laden was “very disappointed” that the towers did not fall. Dabou heard that bin Laden had planned “something spectacular” involving “large scale operations in New York in the summer or fall of 2001.” Moroccan intelligence passed this information to US. Around this time, US intelligence is so interested that they call Dabou to Washington to report on this information in person. Dabout makes the trip in secret, but apparently his cover is blown and he is unable to go back and gather more intelligence. Dabou is still in Washington cooperating with US intelligence agents when 9/11 occurs. After 9/11 he will remain in Washington, get a new identity, and continue to work with US intelligence.

Former CIA agent Robert Baer is advising a prince in a Persian Gulf royal family, when a military associate of this prince passes information to him about a “spectacular terrorist operation” that will take place shortly. He is given a computer record of around 600 secret al-Qaeda operatives in Saudi Arabia and Yemen. The list includes ten names that will be placed on the FBI’s most wanted terrorists list after 9/11. He is also given evidence that a Saudi merchant family had funded the USS Cole bombing on October 12, 2000, and that the Yemeni government is covering up information related to that bombing. At the military officer’s request, he offers all this information to the Saudi Arabian government. However, an aide to the Saudi defense minister, Prince Sultan, refuses to look at the list or to pass the names on (Sultan is later sued for his complicity in the 9/11 plot in August 2002). Baer also passes the information on to a senior CIA official and the CIA’s Counter Terrorism Center, but there is no response or action. Portions of Baer’s book describing his experience wil be blacked out, having been censored by the CIA. [Baer, 2002, pp. 55-58; Financial Times, 1/12/2002]

[Source: Associated Press]At some point between these dates, Israel warns the US that an al-Qaeda attack is imminent. [Fox News, 5/17/2002] Reportedly, two high-ranking agents from the Mossad come to Washington and warn the FBI and CIA that from 50 to 200 terrorists have slipped into the US and are planning “a major assault on the United States.” They say indications point to a “large scale target,” and that Americans would be “very vulnerable.” They add there could be Iraqi connections to the al-Qaeda attack. [Daily Telegraph, 9/16/2001; Ottawa Citizen, 9/17/2001; Los Angeles Times, 9/20/2001] The Los Angeles Times later retracts its story after a CIA spokesperson says, “There was no such warning. Allegations that there was are complete and utter nonsense.” [Los Angeles Times, 9/21/2001] Other newspapers do not retract it.

According to German newspapers, the Mossad gives the CIA a list of 19 terrorists living in the US and say that they appear to be planning to carry out an attack in the near future. It is unknown if these are the 19 9/11 hijackers or if the number is a coincidence. However, four names on the list are known, and these four will be 9/11 hijackers: Nawaf Alhazmi, Khalid Almihdhar, Marwan Alshehhi, and Mohamed Atta. [Die Zeit (Hamburg), 10/1/2002; Der Spiegel (Hamburg), 10/1/2002; BBC, 10/2/2002; Ha'aretz, 10/3/2002] The Mossad appears to have learned about this through its “art student spy ring.” Yet apparently, this warning and list are not treated as particularly urgent by the CIA and the information is not passed on to the FBI. It is unclear whether this warning influenced the decision to add Alhazmi and Almihdhar to a terrorism watch list on this same day, and if so, why only those two. [Der Spiegel (Hamburg), 10/1/2002] Israel has denied that there were any Mossad agents in the US. [Ha'aretz, 10/3/2002]

The 9/11 Commission later will note that at this time, an unnamed foreign intelligence “service report[s] that [al-Qaeda deputy leader] Abu Zubaida [is] considering mounting terrorist attacks in the United States, after postponing possible operations in Europe. No targets, timing or method of attack [are] provided.” Newsweek will suggest that most or all of this information may have come from a US debriefing of al-Qaeda bomber Ahmed Ressam in May 2001 (see May 30, 2001). Newsweek will note that it is a common occurrence for foreign intelligence agencies to “simply rereport to the CIA what it had originally learned from the FBI through separate channels.” Still, even “the multiple channels for Ressam’s warnings [do] little to change thinking within the FBI or CIA…” [Newsweek, 4/28/2005; US District Court of Eastern Virginia, 5/4/2006, pp. 6 pdf file] However, it is possible the information could be more than a mirror of what Ressam said, since a number of Western intelligence agencies are monitoring Zubaida’s phone calls before 9/11 (see October 1998 and After).

A Cayman Islands radio station receives an unsigned letter claiming that three men from either Pakistan or Afghanistan who are living in the Cayman Islands are agents of Osama bin Laden. These three men were briefly arrested in June 2001 for discussing hijacking attacks in New York City (see June 4, 2001). The letter’s anonymous author warns that the men “are organizing a major terrorist act against the US via an airline or airlines.” On September 6, the letter will be forwarded to a Cayman government official, but no action will be taken until after 9/11. When the Cayman government notifies the US is unknown. Many criminals and/or businesses use the Cayman Islands as a safe, no tax, no-questions-asked haven to keep their money. The author of the letter will meet with the FBI shortly after 9/11 and will claim his information was a “premonition of sorts.” The three men will later be arrested. What happens to them after their arrest is unclear. [Miami Herald, 9/20/2001; Los Angeles Times, 9/20/2001; MSNBC, 9/23/2001]

According to Egyptian President Hosni Mubarak, Egyptian intelligence warns American officials that bin Laden’s network is in the advanced stages of executing a significant operation against an American target, probably within the US. [Associated Press, 12/7/2001; New York Times, 6/4/2002] He says he learned this information from an agent working inside al-Qaeda. US officials will deny receiving any such warning from Egypt.

French intelligence gives a general terrorist warning to the US; apparently, its contents echo an Israeli warning from earlier in the month (see August 8-15, 2001). The warning allegedly says that many al-Qaeda operatives have slipped into the US and are planning “a major assault on the United States.” Indications point to a “large scale target.” [Fox News, 5/17/2002]

“On or around” this day, the Mossad give their “latest” warning to the US of a major, imminent attack by al-Qaeda, according to sources close to Mossad. One former Mossad agent says, “My understanding is that the warning was not specific. No target was identified. But it should have resulted in an increased state of security.” US intelligence claims this never happened. [Sunday Mail, 9/16/2001]

The French newspaper Le Figaro will report in late 2001 that on this day, “According to Arab diplomatic sources as well as French intelligence, very specific information [is] transmitted to the CIA with respect to terrorist attacks against American interests around the world, including on US soil.” A French intelligence report sent to the US this day “enumerates all the intelligence, and specifies that the order to attack [is] to come from Afghanistan.” [Le Figaro (Paris), 10/31/2001] It will later be revealed that Khalid Shaikh Mohammed gives Mohamed Atta the final go-ahead in a phone call from Afghanistan the day before 9/11 (see September 10, 2001).

Father Jean-Marie Benjamin.
Father Jean-Marie Benjamin. [Source: Public domain]At a wedding in Todi, Italy, Father Jean-Marie Benjamin is told of a plot to attack the US and Britain using hijacked airplanes as weapons. He is not told specifics regarding time or place. He immediately passes what he knows to a judge and several politicians. He later will state, “Although I am friendly with many Muslims, I wondered why they were telling me, specifically. I felt it my duty to inform the Italian government.” Benjamin has been called “one of the West’s most knowledgeable experts on the Muslim world.” Two days after 9/11, he will meet with the Italian Foreign Minister on this topic. He will say he learned the attack on Britain failed at the last minute. [Zenit (Vatican), 9/16/2001] An al-Qaeda cell based in nearby Milan, Italy, appears to have had foreknowledge of the 9/11 attacks (see August 12, 2000) and (see January 24, 2001). It is not known if the Italian government warns the US government of this latest warning before 9/11.

A month after 9/11, the New York Times will report: “Interpreting intercepted communications, which are cryptic and in code, and sorting through all the rumors present a formidable challenge. One intercept before the Sept. 11 attack was, according to two senior intelligence officials, the first early warning of the assault and it set off a scramble by American and other intelligence agencies. In that call, Mr. bin Laden advised his wife in Syria to come back to Afghanistan. That message, which was intercepted by the intelligence services of more than one country, was passed on to the United States, officials from three countries said.” [New York Times, 10/21/2001] Bin Laden apparently makes a similar phone call to his stepmother in Syria on September 9, 2001 (see September 9, 2001).
