On 20 October 2011, Muammar Gaddafi was killed while attempting to flee the Battle of Sirte at the end of the war. NATO forces involved in the military intervention in Libya were among the participants in the battle, and warplanes and at least one unmanned aerial vehicle operated by coalition partners struck Gaddafi's convoy, leaving him seriously injured and forcing him to abandon his retreat from the city. Opposition fighters located Gaddafi and took him into custody later that day, but he died from a gunshot wound to the head before reaching the hospital in Misrata.
