1996: Germans Begin Investigating Hamburg Cell Member after Tip from Turkey

Mohammed Haydar Zammar. [Source: Knut Mueller]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.
