On the evening of September 11, 2012, Islamic militants attacked the American diplomatic compound in Benghazi, Libya, killing U.S. Ambassador J. Christopher Stevens and U.S. Foreign Service Information Management Officer Sean Smith. Stevens was the first U.S. Ambassador killed on duty since 1979. Several hours later, a second assault targeted a different compound about one mile away, killing two CIA contractors, Tyrone S. Woods and Glen Doherty. Ten others were also injured in the attacks. Many Libyans condemned the attacks and praised the late ambassador. They staged public demonstrations condemning the militias, which were suspected of the attacks. The United States immediately increased security worldwide at diplomatic and military facilities and began investigating the Benghazi attack. In the aftermath of the attack, State Department officials were criticized for denying requests for additional security at the consulate prior to the attack. As Secretary of State, Hillary Clinton subsequently took responsibility for the security lapses.
