August 1997: US Intelligence Monitoring Cell in Kenya Discovers Al-Qaeda Operatives around the World

On August 2, 1997, the Telegraph reports that Tayyib al-Madani, a chief financial officer for bin Laden, turned himself in to the Saudis in May 1997 (see May 1997). Later in the month, US agents raid Wadih El-Hage’s house in Nairobi, Kenya (see August 21, 1997). El-Hage and and Fazul Abdullah Mohammed (a.k.a. Haroun Fazul), both members of the al-Qaeda cell in Nairobi, Kenya, start a flurry of phone traffic, warning other operatives about the raid and the defection. Their phones are already being monitored by the CIA and NSA (see May 21, 1996), who continue to listen in as they communicate nearly every day with al-Qaeda operatives in places such as Afghanistan, Pakistan, London, and Germany. They also phone other members of their cell in Mombasa, Kenya. It appears they realize their phones are being bugged because at one point Fazul explicitly warns an operative in Hamburg, Germany, Sadek Walid Awaad (a.k.a. Abu Khadija), to stop calling because the lines are bugged. However, US intelligence is able to learn much just from the numbers and locations that are being called. For instance, the call to Awaad alerts US intelligence to other operatives in Hamburg who know the 9/11 hijackers living there (see Late 1997).
