A U.S. service member who was part of the coalition fighting Islamic State was killed in a rocket attack in northern Iraq, a U.S. defense official said on Saturday, Reuters reported.
The official said two rockets were fired at a base in Makhmur, a town between the cities of Mosul and Kirkuk. One of the rockets did not cause any damage the official said.
The official added that other personnel had been wounded but did not give any further details.
In October, Master Sergeant Joshua Wheeler, 39, of Roland, Oklahoma, became the first American to die in combat in Iraq since 2011 when he was killed during an overnight mission to rescue hostages held by Islamic State militants.
Earlier this year U.S. Defense Secretary Ash Carter announced that a new U.S. force of special operations troops had arrived in Iraq and was preparing to work with Iraqi forces to go after Islamic State targets.
While that force was expected to number only about 200, its deployment marked the latest expansion of U.S. military pressure on Islamic State.
