US intelligence began monitoring Ali Mohamed in the autumn of 1993 (see Autumn 1993). The San Francisco Chronicle will later report that from “1994 to 1998… FBI agents trace phone calls from Mohamed’s California residences in Santa Clara and, later, Sacramento to bin Laden associates in [Nairobi, Kenya].” In late 1994, FBI agents discover that Mohamed is temporarily living in an al-Qaeda safe house in Nairobi. The FBI contacts him there and he returns to the US a short time later to be interviewed by the FBI (see December 9, 1994). [San Francisco Chronicle, 9/21/2001] When Mohamed is making arrangements to be interviewed by the FBI, he uses the telephone of Wadih El-Hage, bin Laden’s personal secretary who is part of the Kenya al-Qaeda cell. [United States of America v. Usama Bin Laden, et al., Day 39, 5/3/2001] By 1996, US intelligence is continually monitoring five telephone lines in Nairobi used by the cell members, including those belonging to El-Hage (see April 1996).
