In 1983 fighting between Palestinian refugees and Lebanese factions reignited that nation's long-running civil war. A UN agreement brought an international force of peacekeepers to occupy Beirut and guarantee security. US Marines landed in August 1982 along with Italian and French forces. On October 23, 1983, a suicide bomber driving a truck filled with 6 tons of TNT crashed through a fence and destroyed the Marine barracks, killing 241 Marines; seconds later, a second bomber leveled a French barracks, killing 58. Subsequently the US Navy engaged in bombing of militia positions inside Lebanon. While US President Ronald Reagan was initially defiant, political pressure at home eventually forced the withdrawal of the Marines in February 1984.
