February 1999: Monitored Al-Qaeda Cell Member Temporarily Lives in Apartment with 9/11 Hijacker Atta and Other Key Cell Members

Monitored al-Qaeda Hamburg cell member Mohammed Haydar Zammar temporarily lives with future 9/11 hijacker Mohamed Atta and 9/11 hijacker associates Said Bahaji and Ramzi bin al-Shibh. They live in a four bedroom apartment at 54 Marienstrasse, in Hamburg, Germany (see November 1, 1998-February 2001). This is according to a September 2001 memo from the BfV (Germany’s domestic intelligence agency), so it may come from surveillance conducted before 9/11. It is not known why Zammar lives here at this time, since he has his own wife and family in Hamburg; nor is it known how many days he stays at the apartment. [Vanity Fair, 11/2004] Zammar is under surveillance by the BfV at this time (see March 1997-Early 2000), and he is likely under surveillance by the CIA as well (see Shortly After September 16, 1998 and Summer 1999).
