CAIRO — Libyans tried to save Ambassador Chris Stevens, cheering “God is great” and rushing him to a hospital after they discovered him still clinging to life inside the U.S. Consulate, according to witnesses and a new video that emerged Monday from last week’s attack in the city of Benghazi.

The group of Libyans had stumbled across Stevens’ seemingly lifeless form inside a dark room and didn’t know who he was, only that he was a foreigner, the man who shot the video and two other witnesses told The Associated Press.

The account underlines the confusion that reigned during the assault by protesters and heavily armed gunmen that overwhelmed the consulate in Benghazi last Tuesday night, killing four Americans, including Stevens, who died from smoke inhalation soon after he was found. U.S. officials are still trying to piece together how the top American diplomat in Libya got separated from others as staffers were evacuated, suffocating in what is believed to be a consulate safe-room.

The Libyans who found him expressed frustration that there was no ambulance and no first aid on hand, leaving him to be slung over a man’s shoulder to be carried to a car.

“There was not a single ambulance to carry him. Maybe he was handled the wrong way,” said Fahd al-Bakoush, a freelance videographer who shot the footage.

U.S. and Libyan officials are rying to determine who was behind the attack. Still unclear was whether it had been planned beforehand or was sparked by an anti-Islam film made in the United States that, hours before had sparked protests at the American Embassy in Cairo.

On Sunday, Libyan President Mohammed el-Megarif contended foreign militants had been plotting the attack for months and timed it for Tuesday’s 9/11 anniversary.

However, U.S. Ambassador to the U.N. Susan Rice said it appeared spontaneous and unplanned, that extremists with heavier weapons “hijacked” the protest and turned it into an outright attack. She noted Libya is awash with weapons.

Soon after the attack, Libyan civilians roamed freely around the trashed consulate, its walls blacked and furniture burned. Among them were the videographer al-Bakoush, and a photographer and art student he often works with.

They heard a panicked shout, “I stepped over a dead man,” and rushed to see what was going on, al-Bakoush said. The body had been found inside a dark room with a locked door accessible only by a window. A group of men pulled him out and realized he was a foreigner and still alive.

He was breathing and his eyelids flickered, al-Bakoush said.

Video taken by al-Bakoush and posted on YouTube shows Stevens being carried out of the room through a window with a raised shutter. “Bring him out, man,” someone shouts. “Out of the way, out of the way!”

“Alive, Alive!” come other shouts, then a cheer of “God is great.”
