CAIRO, Egypt (AP) – 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.

At the end of the 10-minute 41-second video, the identification cards of the two missing soldiers were shown, with the headline: “Bush is the reason of the loss of your POWs” written on the screen above the cards. SITE did not say how it obtained the video, which featured the logo of media production house of the Islamic State of Iraq.

Along with the identification cards, the footage also showed credit cards, American and Iraqi money and other personal items that they called the militants called the “booty.”

The video also showed footage, apparently taken before the ambush, of three masked men standing around a stand displaying a sketch of the area, mapping out the attack plan. One of the three men, who were all dressed in black, talked to the camera and pointed to the sketch. Another stood by him carrying a gun.

“I have urged you to bring me American prisoners. We will review now a previously prepared study in our zone to bring the enemy to a good area, and with God’s help we will be able to storm their place and capture them at night,” said the man, whose name was not given but was identified as one of the militant group’s leaders.
