A vehicle was engulfed in flames inside the US consulate compound in Benghazi late on Sep. 11, 2012.

On Sept. 11, 2012, heavily armed Islamist militants launched an organized attack on the US diplomatic mission in Benghazi, Libya. The attackers then launched mortar rounds at the CIA annex, setting fire to buildings before US personnel could escape or reinforcements could arrive. Ambassador J. Christopher Stevens and three other Americans were killed in the violence, making it the first time since 1979 that a US ambassador was killed in the line of duty. On June 15, 2014, US Special Operations forces captured one of the suspected ringleaders of the attacks.

Here is how the events played out on the night of the attack.

9:40 p.m.: Unidentified gunmen launch an assault on the US diplomatic compound in the eastern Libyan city of Benghazi, quickly overwhelming the US and Libyan forces who were providing security. Inside the compound, security forces are separated from US Ambassador J. Christopher Stevens. US personnel who retreat to an annex come under siege for two hours before Libyan security forces repel the attackers. Three Americans are killed at the compound, and three others are wounded.

10:30 p.m.: Stevens and State Department security official Sean Smith have taken refuge in the main villa in the compound, behind a fortified door with metal bars that keeps the attackers from breaking in. But the militants set fire to the building. Within minutes, Stevens and Smith are overwhelmed by smoke.

11 p.m.: A US surveillance drone arrives over Benghazi. Then-Defense Secretary Leon Panetta and Gen. Martin Dempsey, chairman of the Joint Chiefs of Staff, meet with President Barack Obama.

1 a.m.: A US rescue team arrives in Benghazi from Tripoli, Libya’s capital. Nearly 30 Americans are rescued from the compound. Shortly thereafter, Stevens is taken to Benghazi Medical Center and pronounced dead on arrival, according to a hospital source. (A Libyan doctor told the Associated Press that Stevens died of asphyxia, probably caused by smoke inhalation. US officials said they will not know for sure until an autopsy is performed.)

1:45 a.m.: The AP moves a news alert, reporting the death of at least one American in the Benghazi attack.

4 a.m.: Gunmen launch an assault using mortars against the CIA annex. Glen Doherty and Tyrone Woods, both former Navy SEALs, are killed.

4:08 a.m.: Secretary of State Hillary Rodham Clinton issues a statement on the attack in Benghazi. ‘‘I condemn in the strongest terms the attack on our mission in Benghazi today. . . . The United States deplores any intentional effort to denigrate the religious beliefs of others. Our commitment to religious tolerance goes back to the very beginning of our nation. But let me be clear: There is never any justification for violent acts of this kind.’’

Sept. 12, 2012

Obama announces that Stevens was among those killed in the Benghazi attack. In his statement, the president says, ‘‘I strongly condemn the outrageous attack on our diplomatic facility in Benghazi.’’ His statement also says: ‘‘While the United States rejects efforts to denigrate the religious beliefs of others, we must all unequivocally oppose the kind of senseless violence that took the lives of these public servants.’’

October 2012

Ahmed Abu Khattala, a ‘‘senior leader’’ of the Benghazi branch of the militant group Ansar al-Sharia, is identified as one of the ringleaders of the attack.
