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).
