Zacarias Moussaoui travels to Baku, Azerbaijan. It is not known why he is there, but Baku is often a staging area for people attempting to go to nearby Chechnya, and there is an important al-Qaeda/Islamic Jihad cell there at the time (see Late August 1998). He meets a CIA informer there, but the informer does not learn Moussaoui’s real name, and does not report on Moussaoui to the CIA until April 2001 (see April 2001). [Tenet, 2007, pp. 201]
