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]
1993: Darkazanli Gives CIA First Hint of Al-Qaeda Cell in Hamburg
According to CIA documents, US intelligence first becomes aware of Mamoun Darkazanli at this time, when a person arrested in Africa carrying false passports and counterfeit money is found with Darkazanli’s telephone number. Darkazanli is a Syrian businessman residing in Germany. The CIA carefully scrutinizes Darkazanli and his business dealings, but authorities are not able to make a case against him. [US Congress, 7/24/2003, pp. 185 
] Many will later claim that Darkazanli is a member of the Hamburg al-Qaeda cell. He will associate with 9/11 hijackers Mohamed Atta, Marwan Alshehhi, and others (see October 9, 1999).
1995-2000: Monitored Al Jazeera Reporter Allegedly Couriers Money from Spain to Turkey, Chechnya, and Afghanistan for Militants
Al Jazeera reporter Tayseer Allouni makes several trips to Turkey and Afghanistan, taking money with him and giving it to people who are later said to be militants. Allouni, some of whose telephone conversations are recorded by Spanish authorities from the mid-1990s (see 1995 and After), makes numerous trips to Turkey and Afghanistan, carrying no more than $4,000 each time. Allouni’s associates include Mamoun Darkazanli and Mohammed Haydar Zammar, who are linked to 9/11 hijackers Mohamed Atta, Marwan Alshehhi, and Ziad Jarrah (see November 1, 1998-February 2001 and October 9, 1999), as well as Spain-based al-Qaeda operative Barakat Yarkas, who also is in contact with Darkazanli and Zammar (see August 1998-September 11, 2001). [Miles, 2005, pp. 306-313] In 2000, Allouni is monitored by the Spanish government as he makes several trips to Afghanistan. His lawyer will later concede that he was given $35,000 by Yarkas, and Allouni will acknowledge that he did carry thousands of dollars from Yarkas to Afghanistan, Turkey, and Chechnya. [Chicago Tribune, 10/19/2003] However, Allouni will later say he is not a member of al-Qaeda and was only taking the money to friends and other Syrian exiles. He will later interview Osama bin Laden (see October 20, 2001) and be sentenced to jail for his alleged al-Qaeda membership (see September 26, 2005). [Miles, 2005, pp. 306-313]
1995-1998: Darkazanli Receives Large Sums From Saudi Intelligence Front Company
A Saudi company called the Twaik Group deposits more than $250,000 in bank accounts controlled by Mamoun Darkazanli, a Syrian-born businessman suspected of belonging to the Hamburg, Germany, al-Qaeda cell that Mohamed Atta is also a part of. In 2004, the Chicago Tribune will reveal evidence that German intelligence has concluded that Twaik, a $100 million-a-year conglomerate, serves as a front for the Saudi Arabian intelligence agency. It has ties to that agency’s longtime chief, Prince Turki al-Faisal. Before 9/11, at least two of Twaik’s managers are suspected by various countries’ intelligence agencies of working for al-Qaeda. One Egyptian employee at Twaik, Reda Seyam, who is later accused of helping to finance the financing of the 2002 Bali bombings (see October 12, 2002), repeatedly flies on aircraft operated by Saudi intelligence. In roughly the same time period, hundreds of thousands of additional dollars are deposited into Darkazanli’s accounts from a variety of suspicious entities, including a Swiss bank owned by Middle Eastern interests with links to terrorism and a radical Berlin imam. Darkazanli is later accused not just of financially helping the Hamburg 9/11 hijackers, but also of helping to choose them for al-Qaeda. [Chicago Tribune, 10/12/2003; Chicago Tribune, 3/31/2004]
1995-1996: Hijacker Associate Bin Al-Shibh Fights in Bosnia
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.
1995-September 16, 1998: Important Al-Qaeda Leader Makes Trips to Germany, Attends Hamburg Mosque Also Attended by 9/11 Hijackers
Al-Qaeda leader Mamdouh Mahmud Salim (a.k.a. Abu Hajer) makes frequent visits to Hamburg, Germany, and sometimes attends the Hamburg mosque that is attended by a few of the future 9/11 hijackers. [Vanity Fair, 1/2002] The 9/11 Congressional Inquiry will later say that Salim was Osama bin Laden’s “right hand man.” [US Congress, 7/24/2003, pp. 51 ] Starting in 1995, Salim makes frequent visits to Germany. Some of these trips are to Hamburg. Salim has links to Mamoun Darkazanli, who lives in Hamburg and has signing powers over Salim’s bank account. [Vanity Fair, 1/2002] Salim first opens a bank account in Hamburg with Darkazanli in 1995. [Boston Globe, 10/6/2001] Darkazanli is also friends with Mohammed Haydar Zammar. Salim has links to Zammar as well. The nature of these links is unclear, but US and German intelligence will later investigate Zammar due to his links with Salim (see Shortly After September 16, 1998). [Der Spiegel (Hamburg), 12/12/2005] Zammar and Darkazanli both regularly attend the Al-Quds mosque in Hamburg. When Salim visits Hamburg, he attends the Al-Quds mosque as well. [Vanity Fair, 1/2002] Beginning in early 1996, future 9/11 hijacker Mohamed Atta and other members of his future al-Qaeda Hamburg cell begin regularly attending the Al-Quds mosque, with different members joining at different times (see Early 1996). The mosque holds about 150 people for Friday prayers. [McDermott, 2005, pp. 1-5] It is not known if Salim ever meets with Atta or any other members of the Hamburg cell. But Zammar, at least, is considered part of the cell, and he or Darkazanli could have introduced Salim to some of the others. One key member of the cell, Said Bahaji, is frequently seen at the Al-Quds mosque with Zammar and Darkazanli. [McDermott, 2005, pp. 72] On September 16, 1998, Salim is arrested in Munich, Germany, ending any link he might have had to the al-Qaeda Hamburg cell (see September 16, 1998). It is not known if US or German investigators ever learn of the link between Salim and the Al-Quds mosque before 9/11.
1996: Germans Start Money Laundering Investigation into Al-Qaeda Hamburg Cell Figures Darkazanli and Zammar
In 1996, German authorities begin investigating Mamoun Darkazanli, Mohammed Haydar Zammar, and four others for money laundering. The investigation apparently begins with Darkazanli and four unnamed others, and grows to incorporate Zammar. Darkazanli and Zammar are friends, and both are closely linked to the al-Qaeda Hamburg cell. The investigation is run by the Bundeskriminalamt (BKA), Germany’s federal crime investigation agency. In late 1998, Darkazanli will be increasingly suspected for various other terrorism ties. But in early 2000, chief federal prosecutor Kay Nehm will refuse to initiate terrorism investigation proceedings against him, saying there is not enough evidence. Prior to 9/11, German law makes it hard to convict anyone for a terrorism offense unless it can be proven they were involved in an attack on German soil. However, Der Spiegel will later note that while that was true, Darkazanli could have been charged with money laundering instead. The money laundering investigation will resume shortly after 9/11. [Der Spiegel (Hamburg), 10/29/2001]
1996: Spanish Intelligence Links Al-Qaeda Leader to Hamburg Cell
Spanish intelligence learns that al-Qaeda leader Mustafa Setmarian Nasar, a.k.a. Abu Musab al-Suri, has visited Mamoun Darkazanli in Hamburg this year. Darkazanli is an associate of the 9/11 hijackers living in Hamburg. The Spanish are aware of Nasar due to his links to Barakat Yarkas, as Yarkas and his Madrid cell are being monitored (see 1995 and After). It is unknown if the Spanish realize that Nasar is an important al-Qaeda leader at this time, but they do learn that he met Osama bin Laden. [National Review, 5/21/2004; Brisard and Martinez, 2005, pp. 109-110, 195] Nasar receives $3,000 from Darkazanli while living in Britain in 1995 through 1996. This is according to German police documents, and it is unknown if German and/or Spanish authorities are aware of this link at the time. [Chicago Tribune, 7/12/2005] In 1998, the Spanish will discover that Darkazanli and Yarkas are in frequent phone contact with each other. They share their information with the CIA (see August 1998-September 11, 2001). Nasar leaves Britain in 1996 after realizing the British authorities suspect his involvement in a series of 1995 bombings in France (see July-October 1995). [National Review, 5/21/2004] He will be arrested in Pakistan in 2005 after the US announces a $5 million reward for his capture (see October 31, 2005).
Early 1996: Future 9/11 Hijackers Begin Attending Radical Mosque Possibly Monitored by German Authorities
Future 9/11 hijacker Mohamed Atta and other members of the Hamburg cell begin regularly attending the Al-Quds mosque. Atta becomes a well-known figure both there and at other mosques in the city. He grows a beard at this time, which some commentators interpret as a sign of greater religious devotion. The mosque is home to numerous radicals. For example, the imam, Mohammed Fazazi, advocates killing non-believers and encourages his followers to embrace martyrdom (see 1993-Late 2001 and Early 2001).
Atta Teaches Classes at Al-Quds – After a time, Atta begins to teach classes at the mosque. He is stern with his students and criticizes them for wearing their hair in ponytails and gold chains around their necks, as well as for listening to music, which he says is a product of the devil. If a woman shows up, her father is informed she is not welcome. This is one of the reasons that, of the 80 students that start the classes, only a handful are left at the end.
Other Hijackers and Cell Members Attend Al-Quds – One of Atta’s associates, Ramzi bin al-Shibh, also teaches classes at the mosque. 9/11 hijackers Marwan Alshehhi and Ziad Jarrah start attending the mosque at different times and possibly first meet Atta there. Other mosque attendees who interact with the future hijackers at the mosque include Said Bahaji, and al-Qaeda operatives Mamoun Darkazanli and Mohammed Haydar Zammar.
Is the Mosque Monitored? – According to author Terry McDermott, German investigators notice Bahaji meeting frequently with Darkazanli and Zammar at the mosque, so they presumably have a source inside it. [PBS Frontline, 1/2002; Burke, 2004, pp. 242; McDermott, 2005, pp. 1-5, 34-37, 72] The German newspaper Frankfurter Allgemeine Zeitung will later report that there probably is an informer working for the LfV, the Hamburg state intelligence agency, inside the mosque by 1999. Somehow, the LfV is very knowledgeable about Atta and some his associates, and their behavior inside the mosque (see (April 1, 1999)). [Frankfurter Allgemeine Zeitung (Frankfurt), 2/2/2003] Radical imam Fazazi will continue to preach at the mosque until late 2001 (see Mid-September-Late 2001).
June 25, 1996: Khobar Towers in Saudi Araiba Are Bombed; Unclear Who the Culprit Is
Explosions destroy the Khobar Towers in Dhahran, Saudi Arabia, killing 19 American soldiers and wounding 500. [CNN, 6/26/1996] Saudi officials will later interrogate the suspects, declare them guilty, and execute them—without letting the FBI talk to them. [PBS Frontline, 2001; Irish Times, 11/19/2001] Saudis will blame Hezbollah, the Iranian-influenced group, but US investigators will still believe Osama bin Laden was involved. [Seattle Times, 10/29/2001] US intelligence will be listening when al-Qaeda’s number two leader Ayman al-Zawahiri calls bin Laden two days after the bombing to congratulate him on the operation (see June 27, 1996). The New York Times will report that Mamoun Darkazanli, a suspected al-Qaeda financier with extensive ties to the al-Qaeda Hamburg cell, is involved in the attack. [New York Times, 9/25/2001; New York Times, 9/29/2001] Bin Laden will admit to instigating the attacks in a 1998 interview. [Miami Herald, 9/24/2001] Ironically, the bin Laden family’s construction company will be awarded the contract to rebuild the installation. [New Yorker, 11/5/2001] In 1997, Canada will catch one of the Khobar Towers attackers and extradite him to the US. However, in 1999, he will be shipped back to Saudi Arabia before he can reveal what he knows about al-Qaeda and the Saudis. One anonymous insider will call it “President Clinton’s parting kiss to the Saudis.” [Palast, 2002, pp. 102] In June 2001, a US grand jury will indict 13 Saudis for the bombing. According to the indictment, Iran and Hezbollah were also involved in the attack. [US Congress, 7/24/2003]
