On this day, 23 Oct 1983, Suicidal terrorists drove a truck loaded with TNT into the U.S. Marines headquarters in Beirut, Lebanon.
The explosion killed 241 U.S. personnel. It represented the deadliest single-day death toll for the
United States Marine Corps since the Battle of Iwo Jima of World War II, the deadliest single-day death
toll for the United States military since the first day of the Tet Offensive during the Vietnam War, and the
deadliest single attack on Americans overseas since World War II.
Many French personnel were also killed in a similar attack on their location at the same time.
The terrorist plowed his bomb-laden truck through three guard posts, a barbed-wire fence, and into
the lobby of the Marines Corps headquarters in Beirut, where he detonated a massive bomb, killing
241 marine, navy, and army personnel.
The bomb, which was made of a sophisticated explosive enhanced by gas, had an explosive power equivalent to 18,000 pounds of dynamite. The identities of the embassy and barracks bombers were
not determined, but they were suspected to be terrorists associated with Iran.
