A member of the U.S.-led coalition fighting against Islamic State was killed in an ISIS rocket attack in northern Iraq on Saturday, the U.S. military said in a statement.
The soldier’s nationality was not included in the statement, but Fox News, citing an unnamed defense source, said it was an American.
The statement said the coalition service member had been killed because of “enemy action.”
“It was a lucky strike by ISIS,” the official said..
The Pentagon is expected to make an announcement shortly.
The US-led coalition fighting ISIS released a statement about the attack Saturday morning, but the nationality of the soldier was withheld. It said the soldier was killed by “enemy action,” but was not more specific.
The soldier is the second American killed fighting ISIS since combat operations began in August 2014.
In October, a Delta Force master sergeant was killed during a daring hostage rescue in Iraq.
The death of Army Master Sgt Joshua Wheeler was the first American casualty in Iraq since the withdrawal of US forces in 2011.
There are roughly 3,700 US troops on the ground in Iraq advising the Iraqi Army. Earlier this month, a brigade from the 101st Airborne Division relieved a similar sized brigade from the 82nd Airborne Division.
