For decades, the Middle East has been a hot bed for political unrest. Such was the case in the early-1980s, when the United Nations established a peacekeeping force in Lebanon, in an attempt to settle unrest in the area.
It didn't work. On October 23, 1983, two suicide truck bombs breached the security perimeter of the UN compound that was housing U.S. Marines and French Paratroopers.
Combined, the truck bombs carried 12,000 pounds of TNT. The resulting explosion demolished the compound. 241 U.S. servicemen (220 of them Marines) were killed.
A group called The Islamic Jihad (suspected of being a front for the organization Hezbollah) claimed responsibility, citing America's unwanted presence in the area.
The attack represented the largest, and deadliest, one-day death toll for the Marines since the battle of Iwo Jima in World War II.
