BAGHDAD, Iraq (CNN) -- A U.S. soldier and an Iraqi interpreter were killed by an Iraqi policeman Tuesday in the northern city of Mosul, the U.S. military said.
The shooting took place as U.S. troops met with Iraqi police at a police station, U.S. and Iraqi sources said.
Initial reports suggested four U.S. soldiers and their interpreter were killed, but the U.S. military later said the four soldiers were wounded, not killed. One soldier later died of his injuries, the military said.
The military statement said one Iraqi translator was killed and another was wounded. All the injured were taken to a combat support hospital, the military said.
The names of the victims have not been released.
Maj. Gen. Abdul Karim Khalaf, a spokesman for Iraq's Interior Ministry, confirmed that an interpreter was killed.
He said Iraqi security forces know who the assailant was and where he lives and a serious effort was being mounted to find him.
The attack took place at a meeting at an Iraqi police station in Nineveh province around 2 p.m., the military said. "An investigation is ongoing to determine the cause and nature of the attack," it said.
