Fazul Abdullah Mohammed, a key al Qaeda operative and the mastermind of the 1998 U.S. Embassy bombings in Kenya and Tanzania, was killed last week in Somalia.
Mohammed was on the FBI's Most Wanted Terrorists list for nearly a dozen years after his indictment in New York for his role in the bombings that killed 224 people, including 12 Americans.
More than 900 agents traveled overseas to assist in the recovery of evidence and identify victims at the bombsites. The investigations at that time represented the largest deployment in the FBI's history.
