Video purportedly shows Libyans rushing to aid U.S. ambassador

The chaos is palpable, as a throng of Libyans frantically scramble outside a damaged building. Suddenly, a man's body is carried from inside toward an open window -- and the frenzy and sounds become even more urgent, more emotional, CNN reports.

"Get him out!" some yell.

After joyfully discovering the man -- a foreigner, apparently, a voice in the crowd says -- is alive after he's dragged out, fresh screams ring out.

"Allahu Akbar," which translates from Arabic to "God is great," men in the crowd shout. Others raise fists to the sky, seemingly rejoicing that this man has somehow survived.

According to the man who shot the video, the wounded man shown is Chris Stevens, the late U.S. ambassador to Libya. If true, the grainy images show some of his last moments alive: Stevens was one of four Americans killed last Tuesday in an attack on the U.S. consulate in Benghazi, Libya.
