A US Official Confirms That Nabhan's Body Was Recovered By The Attacking US Forces.

A U.S. commando attack in Somalia has killed an al Qaeda operative who is on the FBI's list of most wanted terrorists, sources tell ABC News.

The dead terrorist, Saleh Ali Nabhan, is believed to have taken part in the 1998 attacks on U.S. embassies in Kenya and Tanzania. He is also believed to have orchestrated the 2002 bombing of a resort hotel in Mombasa, Kenya, and a failed missile attack on an Israeli airliner leaving Mombasa airport.

Several sources tell ABC News at least one U.S. helicopter fired on a convoy carrying suspected al Qaeda targets in southern Somalia. An American official says a U.S. Navy ship was also nearby to monitor the situation and provide assistance if needed.

Ali Nabhan's death has not yet been officially confirmed, but sources tell ABC News that his body is now in U.S. custody.

Ali Nabhan, a 28-year-old Kenyan, is on the FBI's most wanted list for terrorist activities such as the resort and missile attacks as well as participation in the 1998 attack on the U.S. embassies in Kenya and Tanzania.
