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 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).

Three Yemeni men are arrested in Turin, Italy. They are connected to planned attacks on US facilities in Europe. They are members of Islamic Jihad, the Egyptian militant group led by al-Qaeda number two, Ayman al-Zawahiri. Italian police search their apartments and discover beards, wigs, weapons, and contact details for Mohammed Haydar Zammar, a member of the Hamburg al-Qaeda cell. This information is quickly passed to the German domestic intelligence service. Prior to this point, Germany has been investigating Zammar (see March 1997-Early 2000), but apparently they are uncertain if his claims of training in Afghanistan and meeting bin Laden are idle boasts. But after these arrests in Italy, German intelligence will realize Zammar has connections to real terrorists. The surveillance operation on him, and others in the Hamburg cell, will increase in intensity. [Stern, 8/13/2003; Vanity Fair, 11/2004]

German intelligence passes information about Mohammed Haydar Zammar to the CIA. Zammar is a member of al-Qaeda’s cell in Hamburg, Germany, which includes a few of the future 9/11 hijackers. According to a 2005 Der Spiegel article, the CIA has its own undercover agent in Hamburg, because it is “concerned that Hamburg could be developing into a launching pad for volunteers being sent to Afghanistan to support bin Laden in his cause.” Because of this German intelligence, Zammar makes it “onto the Americans’ internal most-wanted list.” [Der Spiegel (Hamburg), 11/21/2005] It is not known exactly when in 1999 Germany gives this information to the CIA, but it gives information on one of the 9/11 hijackers in Hamburg to the CIA in March 1999 (see March 1999). Ironically, around the summer of 1999, the CIA learns that Zammar is in direct contact with a senior al-Qaeda operational coordinator, but it fails to tell German intelligence about this (see Summer 1999).

Monitored al-Qaeda Hamburg cell member Mohammed Haydar Zammar temporarily lives with future 9/11 hijacker Mohamed Atta and 9/11 hijacker associates Said Bahaji and Ramzi bin al-Shibh. They live in a four bedroom apartment at 54 Marienstrasse, in Hamburg, Germany (see November 1, 1998-February 2001). This is according to a September 2001 memo from the BfV (Germany’s domestic intelligence agency), so it may come from surveillance conducted before 9/11. It is not known why Zammar lives here at this time, since he has his own wife and family in Hamburg; nor is it known how many days he stays at the apartment. [Vanity Fair, 11/2004] Zammar is under surveillance by the BfV at this time (see March 1997-Early 2000), and he is likely under surveillance by the CIA as well (see Shortly After September 16, 1998 and Summer 1999).

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).

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).
