An Islamic website aired a new beheading video today, claiming that the man who was beheaded is a CIA operative. A U.S. spokesman says all CIA personnel are accounted for.

The Internet site, which Islamic extremists often use to post tapes and statements, displayed footage of eight militants surrounding a seated man. A sign around the man's neck showed his photograph and carried a message saying he was a CIA agent and what appeared to be an official pass bearing the word "visitor" written in English.

The footage, titled "Video of the beheading of an American CIA operative in Iraq," lasted more than four minutes and included several scenes, including a masked militant holding a large knife to the captive's throat. On the tape, a man was heard telling the captive in Arabic "put down your hand, this is the last time, next time I will gouge your eyes out." Then in English, he tells the captive, "open your eyes, open your eyes."

There are three Americans missing in Iraq: U.S. Army Spc. Keith M. Maupin and civilian contract workers William Bradley and Timothy Bell. Here are some of the gruesome details in the video:
