Cause

Libya's Muammar Gaddafi declared in 1973 that the entire Gulf of Sidra was Libyan territorial waters, drawing a boundary at 32° 30' N he called 'The Line of Death,' and claimed a 62-nautical-mile exclusive fishing zone. The United States rejected this claim, asserting international law allowed free navigation beyond 12 nautical miles from shore.

Event

In March 1986, the U.S. Navy deployed aircraft carrier battle groups into the disputed Gulf of Sidra as part of Operation Prairie Fire, deliberately transiting waters Libya claimed as sovereign territory. The operation was a direct assertion of freedom-of-navigation rights under international maritime law in the Mediterranean Sea.

Consequence

The operation was one in a series of confrontations between U.S. and Libyan forces in the Gulf of Sidra, following the 1981 incident and preceding another in 1989. It underscored ongoing tensions between the United States and Gaddafi's Libya over competing interpretations of territorial waters and international maritime rights.
