Al-Qaida linked insurgents killed three American soldiers after capturing them last month in Iraq, according to a militant video released Monday that claimed to show footage of the ambush.

The video, which was made available to The Associated Press by the Washington-based SITE Institute, showed confused and jerky night battle scenes, and later offered close-ups of two identification cards.

“The Americans sent 4,000 soldiers looking for them,” said an unidentified voice on the video, which was made available to The Associated Press by the Washington-based SITE Institute. “They were alive and then dead.”

The body of one of the soldiers was later found in Iraq’s Euphrates River, but the other two remain missing. Family friends of the missing men said the American military briefed relatives about the video over the weekend.
