Kenyan police have intensified their searches for Al-Qaida members believed to be behind terrorist attacks in Kenya in 1998 and 2004. On Aug. 7, 1998, an al-Qaida bomb exploded at the U.S. Embassy in Nairobi. The attack killed 224 people and injured 5,000. Four years later, on Nov. 29, 2002, 10 Kenyans and three Israelis were killed when an Israeli-owned hotel near Mombassa was attacked and blown up by a car bomb, while a simultaneous rocket attack on an Israeli airliner failed. Al-Qaida reportedly claimed responsibility for the twin attacks.The Daily Nation reported that Kenyan anti-terrorist officials are attempting to locate Mombassans Ahmed Salim Swedan and Saleh Ali Saleh Nabhan. The pair are suspected to have masterminded both the 1998 and 2002 attack. The two are among four al-Qaida members sought by the U.S. Federal Bureau of Investigation. The other two suspects are Kenyans Fahid Mohammed Ally Msalam and Fazul Abdullah Mohammed. The United States has posted a $4 million reward for information leading to the arrest of any of the quartet. Kenyan anti-terrorism officials maintain that ongoing investigations established that there are currently no active al-Qaida cells in Kenya.
