You can narrow or broaden the context of this timeline by adjusting the zoom level. The lower the scale, the more relevant the items on average will be, while the higher the scale, the less relevant the items, on average, will be.

Mohammed Haydar Zammar, who will later be the chief recruiter for and a key member of the al-Qaeda Hamburg cell, travels widely and joins al-Qaeda. Zammar was born in Syria but his family moved to Hamburg, Germany, in 1971. He became a German citizen and renounced his Syrian citizenship about a decade later. By his late teens, he developed a friendship with Mamoun Darkazanli, a fellow Syrian, and both of them joined the Muslim Brotherhood, a radical Muslim group banned in Egypt. Zammar worked as an auto mechanic until about 1991, when he decides to become a full time militant, and he mostly lives on government benefits after that.
Training and Fighting in Afghanistan - In 1991, Zammar goes to Afghanistan and trains at an elite camp linked to Afghan warlord Gulbuddin Hekmatyar. He fights with Hekmatyar’s forces against the Communist Afghan government before returning to Hamburg by the end of 1991.
Active in Many Countries - Over the next five years, he makes about 40 trips out of Germany, often to countries where Islamist militants are fighting. In 1995, he fights in Bosnia with other Arabs against the Serbians. In 1996, he goes to Afghanistan again and formally pledges allegiance to Osama bin Laden and al-Qaeda, according to an unnamed Arab intelligence agency.
His Travels Cause Attention - All of Zammar’s traveling brings him to the attention of Turkish intelligence, and it notifies German intelligence about his radical militant links in 1996 (see 1996). Knowing that his militant activity is not illegal in Germany as long as he is not involved in a plot targeting Germany, Zammar speaks openly about his travels and exploits, and he becomes very well known within the Islamist extremist community in Hamburg. He begins recruiting others to become active militants and attend Afghan training camps. [Washington Post, 9/11/2002; New York Times, 1/18/2003]

1992-1995: KSM Fights and Fundraises in Bosnia

Khalid Shaikh Mohammed (KSM) fights and fundraises in Bosnia. The 9/11 Commission will later state, “In 1992, KSM spent some time fighting alongside the mujaheddin in Bosnia and supporting that effort with financial donations.” [9/11 Commission, 7/24/2004, pp. 147] He reportedly fights with the elite El Mujahid battalion, and gains Bosnian citizenship. [Schindler, 2007, pp. 281] He also works for Egypitska Pomoc, an Egyptian aid group in Zenica, Bosnia, and in 1995 becomes one of its directors. [Playboy, 6/1/2005] KSM mostly lives in Qatar for the next three years (see 1992-1996), but in 1995 he is back fighting in Bosnia as the violence escalates that year. Abdallah bin Khalid al-Thani, Qatar’s Minister of Religious Affairs, underwrites the costs of the trip. [Los Angeles Times, 12/22/2002; 9/11 Commission, 7/24/2004, pp. 147, 488] This second trip to Bosnia means that KSM fights there at the same time as 9/11 hijackers Khalid Almihdhar and Nawaf Alhazmi, though it is not known if they meet (see 1993-1999). The FBI will later suspect that KSM helped build a bomb used to blow up a police station in neighboring Croatia while KSM was in the area (see October 20, 1995).

Reda Seyam.Reda Seyam. [Source: Bild]9/11 hijacker associate Ramzi bin al-Shibh fights in Bosnia. Exact details are unknown, but bin al-Shibh is well known in Islamist militant circles in Bosnia at this time. The ex-wife of Reda Seyam will later recount traveling to Hamburg from Bosnia with bin al-Shibh and Seyam in 1996. Seyam has never been convicted of any serious charge, but he is widely regarded by intelligence officials as one of al-Qaeda’s most important operatives in Europe. During this time period, Seyam works at a car rental agency in Bosnia that is both widely regarded as an al-Qaeda front and is owned by a company, Twaik Group, that will later be seen by German intelligence as a front of the Saudi intelligence agency. Also during this time, the Twaik Group deposits hundreds of thousands of dollars into the bank accounts of Mamoun Darkazanli, who is an associate of bin al-Shibh and other members of the Hamburg cell (see 1995-1998). [Chicago Tribune, 3/31/2004; Schindler, 2007, pp. 281-282] Future 9/11 hijackers Nawaf Alhazmi and Khalid Almihdhar, future 9/11 mastermind Khalid Shaikh Mohammed, and Hamburg cell member Mohammed Haydar Zammar also fight in Bosnia around this time (see 1995, 1992-1995, and 1991-1996), but it is unknown if they meet bin al-Shibh or each other.

Mohammed Haydar Zammar.Mohammed Haydar Zammar. [Source: Knut Mueller]Turkish intelligence informs Germany’s domestic intelligence service that Mohammed Haydar Zammar is a radical militant who has been traveling to trouble spots around the world. Zammar has already made more than 40 journeys to places like Bosnia and Chechnya, and in 1996 he pledges his allegiance to al-Qaeda during a trip to Afghanistan (see 1991-1996). Turkey explains that Zammar is running a dubious travel agency in Hamburg, organizing flights for radical militants to Afghanistan. As a result, by early 1997, German intelligence will launch Operation Zartheit (Operation Tenderness), an investigation of Islamic militants in the Hamburg area. The Germans will use a full range of intelligence techniques, including wiretaps and informants. [Stern, 8/13/2003; Vanity Fair, 11/2004] Operation Zartheit will run for at least three years and connect Zammar to many of the 9/11 plotters (see March 1997-Early 2000).

The French intelligence service Direction Générale de la Sécurité Extérieure (DGSE) is aware that radical Muslims appear to be traveling through Turkey on their way to training in a third country, presumably Afghanistan. DGSE informer Omar Nasiri will later comment: “[T]he DGSE had noticed a lot of men were disappearing from France, men who were under surveillance. They would attend the radical mosques every day and then, suddenly, they were gone. They went to Turkey and disappeared. A few months later they would be back at the mosques in France, but no one knew where they had been in the meantime. The DGSE thought they were at the training camps.” [Nasiri, 2006, pp. 96] Turkish intelligence is also aware militants transit Turkey at this time and informs German intelligence (see 1996). Several of the 9/11 hijackers will also transit Turkey (see Late November-Early December 1999).

Senior al-Qaeda operatives establish a front company called Maram in Istanbul, Turkey, as a travel agency and import-export business. Investigators will later say they suspect that the company may be involved in efforts to obtain material for nuclear weapons and that it provides money and other assistance to radicals traveling between Europe and training camps in Afghanistan. Turkish intelligence and several foreign agencies are aware that militants transit Turkey at this time and some of them are under surveillance (see 1996, 1995-2000, and Mid-1996), but it is unclear whether Maram itself is monitored. The company, which receives a donation of US$ 1.25 million from Saudi businessman Yassin al-Qadi (see January-August 1998), is established by Mamdouh Mahmud Salim, one of al-Qaeda’s founding members (see August 11-20, 1988), who is said to have a history of moving money and shopping for weapons for the organization. A few months later he transfers shares in the company to two other men. One is Wael Hamza Julaidan, a Saudi businessman also said to be a founder of al-Qaeda; the US will officially designate Julaidan a financial supporter of al-Qaeda in 2002 (see September 6, 2002). The other transferee is Mohammed Bayazid, another founder of al-Qaeda and a US citizen who was arrested in the US in 1994 and then let go (see December 16, 1994). [New York Times, 9/19/2002] For a time before November 1998, toll records for the Illinois office of the Benevolence International Foundation (BIF) show telephone contact with a number in Turkey associated with Bayazid. Phone records indicate Bayazid moves to Turkey around April 1998. [USA v. Benevolence International Foundation and Enaam M. Arnaout, 4/29/2002, pp. 16-17 pdf file] US intelligence has been interested in BIF’s ties to al-Qaeda since at least 1993 (see 1993 and 1998), but apparently misses its links to Maram while the company is still open. After Salim is arrested in Germany in 1998 (see September 16, 1998), the company clears out its offices. A neighbor says, “I just came one morning and saw the office was empty. Nobody knows what happen[ed].” [New York Times, 9/19/2002]

German intelligence unsuccessfully attempts to turn Mohammed Haydar Zammar into an informant. In 1996, the Office for the Protection of the Constitution (BfV), Germany’s domestic intelligence service, learned that Zammar had extensive Islamist militant ties (see 1996). In 1997, the BfV starts an investigation into Islamist militants in Hamburg that is centered on Zammar (see March 1997-Early 2000). Apparently, as part of this investigation, two BfV officials meet with him twice and attempt to get him to become an informant. However, Zammar strongly rejects the proposal. He says he will not serve the West, but will only serve Allah and jihad. However, he is careful to note that he is only interested in jihad outside of Germany, because under German law at this time it is not illegal to be a member of a violent militant group as long as all the violence takes place outside of Germany. [Der Spiegel (Hamburg), 11/21/2005] German intelligence will continue monitoring Zammar and many of his associates in Hamburg (see for instance March 1997-Early 2000, October 2, 1998, and July 2001).

[Source: UE-TV]An investigation of al-Qaeda contacts in Hamburg by the Office for the Protection of the Constitution (BfV), Germany’s domestic intelligence service, begins at least by this time (Germany refuses to disclose additional details). The investigation is called Operation Zartheit (Operation Tenderness), and it was started by a tip about Mohammed Haydar Zammar from Turkish intelligence (see 1996). [New York Times, 1/18/2003]
Zammar Linked to Hamburg 9/11 Cell and Bin Laden - It is later believed that Zammar, a German of Syrian origin, is a part of the Hamburg al-Qaeda cell. [Los Angeles Times, 1/14/2003] Zammar will later claim that he recruited 9/11 hijacker Mohamed Atta and others into the cell. [Washington Post, 6/12/2002] German intelligence is aware that he was personally invited to Afghanistan by bin Laden. [Frankfurter Allgemeine Zeitung (Frankfurt), 2/2/2003] The investigation into Zammar allegedly stops in early 2000, after investigators conclude they don’t have enough evidence to convict him of any crime. [Der Spiegel (Hamburg), 11/21/2005]
CIA Involved with Zammar Operation - Vanity Fair will later claim that “A lone CIA agent, the Germans disclose, attempted to work alongside them” in Operation Zartheit, but German “requests for greater information and cooperation from the CIA, they claim, came to naught.” [Vanity Fair, 11/2004] This CIA agent is probably Thomas Volz, who is the CIA’s undercover agent in Hamburg at the time (see December 1999).

Ahmed Alghamdi.Ahmed Alghamdi. [Source: US District Court for the Eastern District of Virginia, Alexandria Division]Under interrogation after 9/11, al-Qaeda manager Khallad bin Attash will indicate that some of the 9/11 hijackers try to get to the conflict in Chechnya from Turkey, but are not able to do so because the Turkey-Georgia border is closed. In Turkey, they stay in guesthouses in places such as Istanbul and Ankara. Turkish intelligence has been aware that militants often transit Turkey for some time, but there are no reports saying that the hijackers are monitored at this time (see 1996). The militants then decide to travel to Afghanistan and perhaps try to enter Chechnya again later. In this context bin Attash mentions the names of Saeed Alghamdi, Satam al Suqami, Waleed and Wail Alshehri, Abdulaziz Alomari, Ahmed Alnami, Hamza Alghamdi, Salem Alhazmi, and Majed Moqed. Ahmed Alghamdi and Saeed Alghamdi also have documentation suggesting travel to a Russian republic. However, the reliability of evidence obtained during the interrogations of figures like bin Attash is questionable due to the unreliable methods used to extract it (see June 16, 2004). [9/11 Commission, 7/24/2004, pp. 233] Some of the lead hijackers transit Turkey (see Late November-Early December 1999). There are also reports that some of the hijackers tell family and friends in Saudi Arabia that they intend to fight in Chechnya, and it appears that some, Khalid Almihdhar, Nawaf Alhazmi, and Salem Alhazmi, may actually see combat there (see 1996-December 2000).

Around this time, US intelligence notes that a man in Hamburg, Germany, named Mohammed Haydar Zammar is in direct contact with one of bin Laden’s senior operational coordinators. Zammar is an al-Qaeda recruiter with links to 9/11 hijacker Mohamed Atta and the rest of the Hamburg terror cell. The US had noted Zammar’s terror links on “numerous occasions” before 9/11. [US Congress, 7/24/2003 pdf file] However, apparently the US does not share their information on Zammar with German intelligence. Instead, the Germans are given evidence from Turkey that Zammar is running a travel agency as a terror front in Hamburg. In 1998, they got information from Italy confirming he is an Islamic militant (see October 2, 1998). However, his behavior is so suspicious that they have already started monitoring him closely (see 1996). [US Congress, 7/24/2003 pdf file; Stern, 8/13/2003] Ironically, also in 1999, German intelligence gives its information on Zammar to the CIA (see 1999).

[Source: London Times]Hamburg cell members Mohamed Atta, Marwan Alshehhi, Ziad Jarrah, Ramzi bin al-Shibh, and possibly Said Bahaji travel to Afghanistan via Turkey and Karachi, Pakistan. They travel along a route often used by one of their associates, al-Qaeda recruiter Mohammed Haydar Zammar, to send potential operatives to Afghanistan for training. Turkish intelligence is aware of the route and informed German intelligence of it in 1996, leading to an investigation of Zammar (see 1996). However, it is unclear whether German or Turkish intelligence register the Hamburg cell members’ travel and how and whether they disseminate and act on this information. Jarrah is reportedly noticed by an intelligence service in the United Arab Emirates on his return journey from Afghanistan (see January 30, 2000). [New York Times, 9/10/2002; CBS News, 10/9/2002; 9/11 Commission, 7/24/2004, pp. 167; McDermott, 2005, pp. 89]

9/11 hijacker Mohamed Atta returns to Germany from Pakistan using the same monitored route as he traveled on the outward journey (see Late November-Early December 1999). He flies from Karachi to Istanbul, Turkey, where he changes planes for Hamburg. Turkish intelligence discovered that militants use this route to travel between Europe and training camps in Afghanistan in the mid-1990s and alerted Germany to it at that time, causing Germany to launch an investigation into one of Atta’s associates (see 1996). However, it is not known whether the intelligence agencies register Atta’s travel at this time. [Stern, 8/13/2003] Fellow alleged 9/11 hijacker Ziad Jarrah appears to be noticed on his way back to Germany from Afghanistan (see January 30, 2000) and another member of the cell, Ramzi bin al-Shibh, may be monitored in Kuala Lumpur, Malaysia, at this time (see January 5-8, 2000).

Al-Qaeda Hamburg cell member Mounir El Motassadeq leaves Germany for Afghanistan and his travel is immediately reported to the German authorities because he is on a watch list (see March 2000). El Motassadeq flies from Hamburg to Karachi, Pakistan, via Istanbul. At least two of the future 9/11 hijackers have previously traveled this route to Afghanistan (see Late November-Early December 1999). Although Turkish intelligence is aware that radicals from Germany travel to Afghanistan via Turkey, it is unclear whether they pick up the travel by El Motassadeq (see 1996). There are two versions of German intelligence’s reaction to this trip. An early 2003 article in Der Speigel will say that the intelligence report only gives El Motassadeq’s destination as Istanbul, so there are no consequences for him. However, a later article in Stern magazine will say, “Naturally, the officials know that Istanbul is not his real destination but only the usual stopover on his way to Afghanistan, to the camps of Osama bin Laden.” [Der Spiegel (Hamburg), 2/3/2003; Stern, 8/13/2003] Indeed, El Motassadeq goes to an al-Qaeda training camp in Afghanistan (see May 22 to August 2000).

Said Berraj.Said Berraj. [Source: Spanish Interior Ministry]Five suspected al-Qaeda operatives, Said Berraj, Amer el-Azizi, Mohamed Haddad, Lahcen Ikassrien, and Salahedin Benyaich, are arrested in Turkey. They are arrested two weeks after arriving in Turkey, apparently for failing to produce identification papers. They are later released, but the reason for releasing them is unknown. Turkey is a transit center and logistics base for al-Qaeda (see November 1996-September 1998 and Mid-1996) and el-Azizi is said to operate there, as well as in Iran and, possibly, Iraq. Berraj, Haddad, and el-Azizi will later be involved in an attack in Madrid, Spain, that kills nearly 200 people (see Before March 11, 2004 and 7:37-7:42 a.m., March 11, 2004) and Benyaich will later be jailed in Morocco on terrorism charges following a bombing in Casablanca (see May 16, 2003). El-Azizi will also apparently be involved in setting up a meeting where details of the 9/11 plot are finalized (see Before July 8, 2001). [Los Angeles Times, 4/14/2004; New York Times, 4/29/2004; New York Times, 4/30/2004; El Mundo (Madrid), 9/14/2004] Ikassrien will be arrested in Afghanistan in late 2001 and sent to the Guantanamo prison. He will be released back to Spain in 2005, charged for al-Qaeda links, an acquitted. [Associated Press, 10/11/2006]
Possible Informants - Berraj is an informant for Spanish intelligence, regularly meeting with intelligence agents in 2003. It is unknown when he begins informing (see Shortly Before March 11, 2004). Haddad will not be arrested in Morocco after the 2004 train bombings despite strong evidence he was directly involved, leading to suspicions that he has been a government informant (see Shortly After March 18, 2004). El-Azizi also will be suspected of being a government informant because he is tipped off by Spanish intelligence about a police raid (see Shortly After November 21, 2001). He is also arrested in Turkey for passport forgery at one point, and then let go, although it is not clear when. [Wall Street Journal, 3/19/2004] Turkish intelligence is aware of extremists’ use of Turkey as a base (see 1996), but it is unclear whether this is related to the arrest of the three men. El-Azizi will repeatedly evade arrest in Spain after 9/11, apparently with the help of Spanish intelligence (see October 2001 and Shortly After November 21, 2001).

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).

[Source: US Department of State]German authorities notify their Spanish counterparts of a trip by Ramzi bin al-Shibh to Spain, where he meets an associate, lead 9/11 hijacker Mohamed Atta (see July 8-19, 2001). Presumably, the notification is before or soon after the trip, but the original news report merely says, “Despite the fact that the German authorities informed Spain of Ramzi’s trip, the meeting in which the 11 September attacks were finalized was not detected.” Several of bin al-Shibh’s German associates are known to have been under surveillance around this time (see 1996, November 1, 1998-February 2001, and May 22, 2000), and, if the article if correct, this indicates that bin al-Shibh’s movements are also being monitored by German intelligence. Spanish authorities are monitoring some operatives who may interact with Atta and bin al-Shibh in Spain (see Before July 8, 2001 and July 8-19, 2001), but the Spanish apparently do not conduct surveillance of the two men.

The 9/11 Congressional Inquiry’s final report concludes that at least six 9/11 hijackers received “substantial assistance” from associates in the US, though it’s “not known to what extent any of these contacts in the United States were aware of the plot.” These hijackers came into contact with at least 14 people who were investigated by the FBI before 9/11, and four of those investigations were active while the hijackers were present. But in June 2002, FBI Director Mueller testified: “While here, the hijackers effectively operated without suspicion, triggering nothing that would have alerted law enforcement and doing nothing that exposed them to domestic coverage. As far as we know, they contacted no known terrorist sympathizers in the United States” (see June 18, 2002). CIA Director Tenet made similar comments at the same time, and another FBI official stated, “[T]here were no contacts with anybody we were looking at inside the United States.” These comments are untrue, because one FBI document from November 2001 uncovered by the Inquiry concludes that the six lead hijackers “maintained a web of contacts both in the United States and abroad. These associates, ranging in degrees of closeness, include friends and associates from universities and flight schools, former roommates, people they knew through mosques and religious activities, and employment contacts. Other contacts provided legal, logistical, or financial assistance, facilitated US entry and flight school enrollment, or were known from [al-Qaeda]-related activities or training.” [US Congress, 7/24/2003 pdf file] The declassified sections of the 9/11 Congressional Inquiry’s final report show the hijackers have contact with:
bullet Mamoun Darkazanli, investigated several times starting in 1993 (see 1993; Late 1998); the CIA makes repeated efforts to turn him into an informer (see December 1999).
bullet Mohammed Haydar Zammar, investigated by Germany since at least 1997 (see 1996), the Germans periodically inform the CIA what they learn.
bullet Osama Basnan, US intelligence is informed of his connections to Islamic militants several times in early 1990s but fails to investigate (see April 1998).
bullet Omar al-Bayoumi, investigated in San Diego from 1998-1999 (see September 1998-July 1999).
bullet Anwar al-Awlaki, investigated in San Diego from 1999-2000 (see June 1999-March 2000).
bullet Osama “Sam” Mustafa, owner of a San Diego gas station, and investigated beginning in 1991 (see Autumn 2000).
bullet Ed Salamah, manager of the same gas station, and an uncooperative witness in 2000 (see Autumn 2000).
bullet An unnamed friend of Hani Hanjour, whom the FBI tries to investigate in 2001.
bullet An unnamed associate of Marwan Alshehhi, investigated beginning in 1999.
bullet Hijackers Nawaf Alhazmi and Khalid Almihdhar, who had contact with Basnan, al-Bayoumi, al-Awlaki, Mustafa, and Salamah, “maintained a number of other contacts in the local Islamic community during their time in San Diego, some of whom were also known to the FBI through counterterrorist inquiries and investigations,” but details of these individuals and possible others are still classified. [US Congress, 7/24/2003 pdf file] None of the above people have been arrested or even publicly charged with any crime associated with terrorism, although Zammar is in prison in Syria.
