On August 7, 1998 truck bombs were detonated at the U.S. embassies in two different East African capital cities: Dar es Salaam, Tanzania, and Nairobi, Kenya. These explosions killed 224 people, wounded more than 4,500, and caused a substantial amount of property damage. Although twelve Americans were killed in these attacks, the vast majority of the casualties were Kenyan civilians. A faction of al-Qaeda was determined to be responsible for the attacks. Al-Qaeda's portrayal within the realm of Western media would go on to become relatively notorious in response to the 1998 bombings; bin Laden was subsequently placed on the Federal Bureau of Investigation (FBI)'s most wanted fugitives list. Prior to the bombings, al-Qaeda was relatively unknown to the Western public. The CIA, however, was well aware of al-Qaeda before the attacks. The al-Qaeda cell in East Africa had even been monitored by the CIA prior to the attacks. The Nairobi Embassy had increased security measures and issued warnings about its vulnerabilities. In addition, representatives from the U.S. were sent to the Nairobi Embassy for security assessments, on multiple occasions, prior to the bombings. The embassy bombings exposed potential U.S. vulnerability to the growing global threat posed by terrorism.
