At least 14 people and possibly up to 10 more are reported to have been killed in fighting in Benghazi May 16 as forces led by Gen. Khalifa Hafter [4] attacked an alliance of Islamist militias [5] made up of the February 17 Brigade, Libya Shield No. 1 Brigade and Ansar al-Sharia [6]. Gen. Hafter's attack on the militias was apparently not approved by the central government in Tripoli, which has disavowed it. Acting Prime Minister Abdullah al-Thinni condemned the operation as "a coup against the revolution." The fighting is the heaviest in Libya since the 2011 revolution. Eye-witnesses describe a city in chaos, with warplanes streaking low over rooftops, tanks on the streets, aerial bombardments and door-to-door combat. The February 17 Brigade claims to have shot down a helicopter used in the attacks. Fighting continues, with with all shops shut and the city virtually closed down—including the internet for much of the day, supposedly due to a short circuit.
