The Pentagon has admitted it lied about the recent deaths of five U.S. troops in the Iraqi city of Karbala. The military initially said the troops died as they repelled an attack by gunmen disguised as American soldiers. But now the military admits only one soldier died during the initial attack. The four other soldiers were abducted from the base and were later shot to death. The Associated Press described the incident as perhaps the boldest and most sophisticated attack of the war. The gunmen all spoke English, wore U.S. military uniforms, carried American weapons and drove black GMC Suburban vehicles.
