Officials: U.S. soldier in Baghdad kills 5 troops

U.S. Army troops get a safety briefing before departing Camp Liberty, Iraq, in December 2008.
A U.S. soldier in Baghdad opened fire on his fellow soldiers Monday, killing five American soldiers, a senior defense official said.

It is unclear if the shooter was among the five dead, despite initial reports that he died, the official said. Three others were wounded in the incident at the U.S. military base, Camp Liberty, in Baghdad, the official said. The U.S. military issued a news release saying only that five coalition soldiers were killed Monday in a shooting at Camp Liberty. The military did not give the soldiers’ nationalities or provide further details.
