Senior State Department officials on Tuesday provided a more detailed picture of the consulate attack in Benghazi, Libya, that killed U.S. Ambassador Chris Stevens and three other Americans. A look at how they say the attack took place:
Sept. 10-11, 2012
Stevens arrives in Benghazi and holds meetings on and off the consulate grounds on Sept. 10. He spends the night, and for the 11th anniversary of the 9/11 attacks on the U.S. holds meetings only inside the compound. It is an enclosed area about 300 yards long by 100 yards wide, with a 9-foot outer wall topped by barbed wire and augmented by barriers, steel drop bars and other security upgrades. There are four buildings in the compound. Five diplomatic security officers are present, along with four members of a local militia deployed by Libya's government to provide added security.
Around 8:30 p.m.
Stevens finishes his final meeting of the day and escorts a Turkish diplomat outside the main entrance of the consulate. The situation is calm. There are no protests.
Around 9:40 p.m.
Agents hear loud noises, gunfire and explosions near the front gate. A barracks at the entrance housing the local militiamen is burnt down. Agents viewing cameras see large group of armed men flowing into the compound. Alarm is sounded. Telephone calls are made to the embassy in Tripoli, officials in Washington, the Libyan authorities and a U.S. quick reaction force located at a second compound a little over a mile away.
One agent, armed with a sidearm and an M4 submachine gun, takes Stevens and computer specialist Sean Smith to a safe room inside one of the compound's two main residences. It has a heavy metal grill and several locks, medical supplies and water, and windows that can be opened only from the inside. The other agents equip themselves with long guns, body armor, helmets and ammunition at other buildings. Two try to make it to the building with Stevens. They are met by armed men and are forced to retreat.
Attackers breach the compound
Attackers penetrate Stevens' building and try to break the grill locks for the safe room, but cannot gain access. They dump jerry cans of diesel fuel in the building, light furniture on fire and set aflame part of the exterior of the building. Two of the remaining four agents are in the compound's other residence. Attackers penetrate that building, but the agents barricade themselves in and the attackers can't reach them. Attackers try to enter the tactical operations center, where the last two agents are located. They smash up the door but cannot enter the building.
Meanwhile, Stevens' building rapidly fills up with thick diesel smoke and burning fumes from the furniture. Inside, visibility is less than 3 feet. Unable to breathe, the Americans go to a bathroom and open a window, but still can't get enough air. They decide to leave the building. The agent goes first, flopping out onto a patio enclosed by sandbags. He takes immediate fire, including probably rocket-propelled grenades. Stevens and Smith don't come out of the building. The agent, suffering severely from smoke inhalation, goes in and out of the building several times to look for them. He then climbs a ladder to the roof of the building and collapses. He radios the other agents to alert them to the situation there.
The other four agents are able to reunite and take an armored vehicle to Stevens' building. They reach the collapsed agent and try to set up a perimeter. They take turns going into the building, searching on hands and knees for the missing Americans. Smith is pulled out, dead. Stevens cannot be found.
A six-person quick reaction security team arrives from their compound across town. About 60 Libyan militiamen accompany them. They attempt to secure a perimeter around Stevens' building, and take turns going inside. Taking fire, Libyan forces determine they can't hold the perimeter. A decision is made to evacuate the compound and return with everyone to the reaction force's compound.
Agents pile into an armored vehicle, with Smith's body, and leave through the main gate. They face immediate fire. Crowds and groups of men block two different routes to the security compound. Heavy traffic means they are traveling only about 15 mph, and trying not to attract attention. On a narrow street they reach a group of men who signal for them to enter a compound. They sense an attack and speed away, taking heavy fire from AK-47 machine guns at a distance of only 2 feet, and hand grenades thrown against and under the car. Two tires are blown out.
They speed past another crowd of men and onto a main street and across a grassy median into opposing traffic. The agents drive against traffic, eventually reaching their compound. Security gets into firing positions around the compound and on the roof. They take more gunfire and rocket-propelled grenades intermittently for several hours.
In the night, a team of reinforcements from the U.S. Embassy in Tripoli arrives on a chartered aircraft at the Benghazi airport and reaches the security compound.
Around 4 a.m.
The compound's building is hit by mortar fire. The roof is hit and two security personnel are killed. One agent involved in the attack from the beginning is severely wounded. The men decide to evacuate the city entirely. They spend the next hours securing the annex and moving a large convoy of vehicles to the airport. They evacuate on two flights.
