US military says 5 US soldiers killed in shooting at American base in Baghdad; Shooter Is Now in Custody.Source
Five U.S. soldiers were killed Monday in a shooting at an American base in Baghdad, the U.S. command said.
A brief U.S. statement said the shooting occurred about 2 p.m. at Camp Liberty near Baghdad International Airport but gave no further details on the attack.
The toll was the highest for U.S. personnel in a single attack since April 10, when a suicide truck driver killed five American soldiers with a blast near a police headquarters in the northern city of Mosul.
On May 2, two American soldiers died after an attacker wearing an Iraqi army uniform opened fire near the northern city of Mosul. The assailant was also killed.
