The man in the video identified himself as Nick Berg.

BAGHDAD, Iraq (May 11) -- A video posted Tuesday on an al-Qaida-linked Web site showed the beheading of an American civilian in Iraq and said the execution was carried out to avenge abuses of Iraqi prisoners at Abu Ghraib prison.

In a grisly gesture, the executioners held up the man's head for the camera.

The American identified himself on the video as Nick Berg, a 26-year-old Philadelphia native. His body was found near a highway overpass in Baghdad on Saturday, the same day he was beheaded, a U.S. official said.
