On October 23, 1983, U.S. and French troops in Beirut were attacked by two suicide truck bombs during the Lebanese Civil War. The bombs exploded minutes apart. The first bomb struck the U.S. Marine barracks, killing 241 service members, and a second bomb hit the building housing French paratroopers, killing 58 soldiers.
The attacks, which claimed a total of 307 lives including civilians, were the deadliest single-day loss for the U.S. Marine Corps since World War II and were carried out by the group Islamic Jihad.
