Police raid the apartment of Cabdullah Ciise, an extremist based in Germany who is linked to hijacker Mohamed Atta and some of his associates in the Hamburg al-Qaeda cell. The police find forged Italian documents in the apartment, proving a link between Ciise in Germany and Italian cells that specialize in document forgery, especially one in Milan that is under investigation (see 1998 and October 2, 1998). Ciise lives in Germany from 1991 until October 1999, during which time he becomes friendly with Mohamed Atta as well as cell member Ramzi bin al-Shibh, with whom he often watches videos about the war in Chechyna and talks about religion. Ciise is also linked to other cell members such as Mohamed Daki and his associates Said Bahaji and Mounir El Motassadeq, as well as a Yemeni named Mohammed Rajih whom German authorities will investigate for terrorist ties at some point before 2005. It is unclear what impact the link to the important Milan cell has on surveillance of the cell in Hamburg. Ciise will allegedly be involved in a bombing in Mombasa, Kenya (see November 28, 2002), will help send fighters to Iraq, and will be arrested in Milan in 2003. [Vidino, 2006, pp. 256]
