On September 11, 2012, at 9:40 p.m. local time, members of Ansar al-Sharia attacked the American diplomatic compound in Benghazi resulting in the deaths of both United States Ambassador to Libya J. Christopher Stevens and U.S. Foreign Service Information Management Officer Sean Smith. At around 4:00 a.m. on September 12, the group launched a mortar attack against a CIA annex approximately one mile (1.6 km) away, killing two CIA contractors Tyrone S. Woods and Glen Dohertyand wounding ten others. Initial analysis by the CIA, repeated by top government officials, indicated that the attack spontaneously arose from a protest. Subsequent investigations showed that the attack was premeditated—although rioters and looters not originally part of the group may have joined in after the attacks began. There is no definitive evidence that al-Qaeda or any other international terrorist organization participated in the Benghazi attack.[10][11][12] The United States immediately increased security worldwide at diplomatic and military facilities and began investigating the Benghazi attack.[13][14] The Libyan Government condemned the attacks and took steps to disband the militias. 30,000 Libyans marched through Benghazi condemning Ansar al-Sharia, which had been formed during the 2011 Libyan civil war to topple Muammar Gaddafi. Despite persistent accusations against President Obama, Hillary Clinton, and Susan Rice, ten investigations—six by Republican-controlled Congressional Committees—did not find that they or any other high-ranking Obama administration officials had acted improperly. Four career State Department officials were criticized for denying requests for additional security at the facility prior to the attack. Eric J. Boswell, the Assistant Secretary of State for Diplomatic Security, resigned under pressure, while three others were suspended. In her role as Secretary of State, Hillary Clinton subsequently took responsibility for the security lapses.
