The Benghazi Attack was a pre-planned armed assault on a United States outpost in Benghazi, Libya on September 11, 2012, in which the American ambassador to Libya, J. Christopher Stevens, and three other members of his diplomatic mission were murdered: Foreign Service Information Management Officer Sean Smith, and private security employees and former U.S. Navy SEALs Glen Doherty and Tyrone S. Woods. The attack also injured two other Americans. The United States initially said that the attack was provoked by an anti-islamic YouTube video, but the facts disproved that.
The attack is being investigated by the State Department as well as by the United States House of Representatives. A House committee hearing on September 10 revealed that the Ambassador and others wished additional security for the consulate, but were turned down.
Approximately a week later the Ansar al-Sharia militia, which was accused of organising the attacks, was driven from its bases in Benghazi by hundreds of protesters with 11 deaths.
