German intelligence is periodically tapping suspected al-Qaeda operative Mohammed Haydar Zammar’s telephone, and on this day investigators hear Zammar call 9/11 hijacker Marwan Alshehhi. Officials initially claim that the call also mentions hijacker Mohamed Atta, but only his first name. [Daily Telegraph, 11/24/2001; New York Times, 1/18/2003] However, his full name, “Mohamed Atta Al Amir,” is mentioned in this call and in another recorded call. [Frankfurter Allgemeine Zeitung (Frankfurt), 2/2/2003] Alshehhi makes veiled references to plans to travel to Afghanistan. He also hands the phone over to Said Bahaji (another member of the Hamburg cell under investigation at the time), so he can talk to Zammar. [Stern, 8/13/2003] German investigators still do not know Alshehhi’s full name, but they recognize this “Marwan” also called Zammar in January, and they told the CIA about that call. Alshehhi, living in the United Arab Emirates at the time, calls Zammar frequently. German intelligence asks the United Arab Emirates to identify the number and the caller, but the request is not answered. [Der Spiegel (Hamburg), 2/3/2003]
