1995-1999: Monitored Al Jazeera Reporter Allegedly Couriers Money from Spain to Turkey 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, makes five or six 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 is in contact with Darkazanli and Zammar (see August 1998-September 11, 2001). 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. Allouni 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]

1996: Germans Begin Investigating Hamburg Cell Member after Tip from Turkey
Turkish intelligence informs German’s domestic intelligence service that Mohammed Haydar Zammar is a radical militant who has been traveling to trouble spots around the world. He has already made more than 40 journeys to places like Bosnia and Chechnya. 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, 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] Apparently, while Zammar was a teenager in Syria, he became friends with Mamoun Darkazanli and the two of them joined the Muslim Brotherhood, a radical Muslim group banned in Egypt. In 1991, Zammar trained and fought in Afghanistan with the forces of the warlord Gulbuddin Hekmatyar. In 1995, he fought in Bosnia against the Serbs, while based in Zenica with other mujaheddin. German intelligence apparently is familiar with at least some of Zammar’s background, because the New York Times will later report that Zammar “had been identified [in the late 1980s] by German authorities as a militant who frequented mosques in Hamburg and elsewhere.” [Washington Post, 9/11/2002; New York Times, 1/18/2003] Operation Zartheit will run at least three years and connect Zammar to many of the 9/11 plotters.

March 1997: German Government Investigates Hamburg Al-Qaeda Cell
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, and it was started by a tip about Mohammed Haydar Zammar from Turkish intelligence (see 1996). [New York Times, 1/18/2003] 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] He later claims he recruited Mohamed Atta and others into the cell [Washington Post, 6/19/2002] From 1995-2000, he makes frequent trips to Afghanistan. [New York Times, 1/18/2003; Stern, 8/13/2003] German intelligence is aware that he was personally invited to Afghanistan by bin Laden. [Frankfurter Allgemeine Zeitung (Frankfurt), 2/2/2003] It is not clear if or when the investigation ends, but it continues until at least September 1999. [Associated Press, 6/22/2002]

August 1998: Germany Investigates Hamburg Al-Qaeda Cell Member
A German inquiry into Mounir El Motassadeq, an alleged member of the Hamburg al-Qaeda cell with Mohamed Atta, begins by this time. Although Germany will not reveal details, documents show that by August 1998, Motassadeq is under surveillance. “The trail soon [leads] to most of the main [Hamburg] participants” in 9/11. Surveillance records Motassadeq and Mohammed Haydar Zammar, who had already been identified by police as a suspected extremist, as they meet at the Hamburg home of Said Bahaji, who is also under surveillance that same year. (Bahaji will soon move into an apartment with Atta and other al-Qaeda members.) German police monitor several other meetings between Motassadeq and Zammar in the following months. [New York Times, 1/18/2003] Motassadeq is later convicted in August 2002 in Germany for participation in the 9/11 attacks, but his conviction is later overturned (see March 3, 2004).

October 2, 1998: Italian Tip Leads to Increased German Surveillance of Hamburg Cell
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), 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]

November 1, 1998-February 2001: Atta and Other Islamic Militants Are Monitored by US and Germany in Hamburg Apartment
Mohamed Atta and al-Qaeda operatives Said Bahaji and Ramzi Bin al-Shibh move into a four bedroom apartment at 54 Marienstrasse, in Hamburg, Germany, and stay there until February 2001 (Atta is already living primarily in the US well before this time). Investigators believe this move marks the formation of their Hamburg al-Qaeda cell [Los Angeles Times, 1/27/2002; New York Times, 9/10/2002] Up to six men at a time live at the apartment, including other al-Qaeda agents such as hijacker Marwan Alshehhi and cell member Zakariya Essabar. [New York Times, 9/15/2001] During the 28 months Atta’s name is on the apartment lease, 29 Middle Eastern or North African men register the apartment as their home address. From the very beginning, the apartment was officially under surveillance by German intelligence, because of investigations into businessman Mamoun Darkazanli that connect to Said Bahaji. [Washington Post, 10/23/2001] The Germans also suspect connections between Bahaji and al-Qaeda operative Mohammed Haydar Zammar. [Los Angeles Times, 9/1/2002] German intelligence monitors the apartment off and on for months, and wiretaps Mounir El Motassadeq, an associate of the apartment-mates who is later put on trial in August 2002 for assisting the 9/11 plot, but apparently do not find any indication of suspicious activity. [Chicago Tribune, 9/5/2002] Bahaji is directly monitored at least for part of 1998, but German officials have not disclosed when the probe began or ended. That investigation is dropped for lack of evidence. [Associated Press, 6/22/2002; Los Angeles Times, 9/1/2002] It is now clear that investigators would have found evidence if they looked more thoroughly. For instance, Zammar, a talkative man who has trouble keeping secrets, is a frequent visitor to the many late night meetings there. [Miller, Stone, and Mitchell, 2002, pp. 259-60; Los Angeles Times, 9/1/2002; Chicago Tribune, 9/5/2002] Another visitor later recalls Atta and others discussing attacking the US. [Knight Ridder, 9/9/2002] 9/11 mastermind Khalid Shaikh Mohammed is in Hamburg several times in 1999, and comes to the apartment. However, although there was a $2 million reward for Mohammed since 1998, the US apparently fails to tell Germany what it knows about him (see 1999). [Newsweek, 9/4/2002; New York Times, 11/4/2002] Hijacker Waleed Alshehri also apparently stays at the apartment “at times.” [Washington Post, 9/14/2001; Washington Post, 9/16/2001] The CIA also starts monitoring Atta while he is living at this apartment, and does not tell Germany of the surveillance. Remarkably, the German government will claim it knew little about the Hamburg al-Qaeda cell before 9/11, and nothing directed them towards the Marienstrasse apartment. [Daily Telegraph, 11/24/2001]

January 31, 1999: Germany Monitors 9/11 Hijacker’s Calls, Shares Information with CIA
German intelligence is tapping the telephone of al-Qaeda operative Mohammed Haydar Zammar, and on this date, Zammar gets a call from a “Marwan.” This is later found to be hijacker Marwan Alshehhi. Marwan talks about mundane things, like his studies in Bonn, Germany, and promises to come to Hamburg in a few months. German investigators trace the telephone number and determine the call came from a mobile phone registered in the United Arab Emirates. [US Congress, 7/24/2003 pdf file; Deutsche Presse-Agentur (Hamburg), 8/13/2003; New York Times, 2/24/2004] German intelligence will pass this information to the CIA about one month later, but the CIA apparently fails to capitalize on it (see March 1999).
