On 2 December 1979, the U.S. Embassy in Tripoli, Libya, was burned during protests over allegations that the United States was involved in the Grand Mosque seizure in Mecca, Saudi Arabia.
The United States had already withdrawn the U.S. Ambassador to Libya in 1972. Following the 1979 attack, all remaining U.S. government personnel were withdrawn and the embassy closed. Diplomatic presence resumed on February 8, 2004, with the arrival of the U.S. Interests Section in Tripoli. That mission was upgraded to a Liaison Office on June 24, 2004.
