German intelligence gives the CIA the first name of 9/11 hijacker Marwan Alshehhi and his telephone number of a phone registered in the United Arab Emirates (UAE). The Germans learned the information from the surveillance of al-Qaeda Hamburg cell member Mohammed Haydar Zammar (see March 1997-Early 2000). They tell the CIA that Alshehhi, who is living in Bonn, Germany, at the time, may be connected to al-Qaeda. He is described as a UAE student who has spent some time studying in Germany. The conversation is short, but a known alias of Mamoun Darkazanli is mentioned. The CIA is very interested in Darkazanli and will try to recruit him as an informant later in the year (see Late 1998 and December 1999).

No Response from CIA – The Germans consider this information “particularly valuable” and ask the CIA to track Alshehhi, but the CIA never responds until after the 9/11 attacks. The CIA decides at the time that this “Marwan” is probably an associate of bin Laden but never track him down. It is not clear why the CIA fails to act, or if they learn his last name before 9/11. [New York Times, 2/24/2004] The Germans monitor other calls between Alshehhi and Zammar, but it isn’t clear if the CIA is also told of these or not (see September 21, 1999).
Could the Number Be Traced? – CIA Director George Tenet will later dismiss the importance of this information in a statement to the 9/11 Congressional Inquiry. He will say that all the CIA had to go on was a first name and an impossible to trace unlisted number. But author Terry McDermott will later comment, “At least a portion of that statement is preposterous. The UAE mobile telephone business was, until 2004, a state monopoly. The UAE number could have been traced in five minutes, according to senior security officials there. The United States never asked.” McDermott will add, “Further, the CIA told the [9/11 Congressional Inquiry] it had a long-standing interest in Zammar that pre-dated these recordings. In other words, the CIA appears to have been investigating the man who recruited the hijackers at the time he was recruiting them.” [McDermott, 2005, pp. 73, 278-279]
