A U.S. Marine who was part of the coalition fighting Islamic State was killed in a rocket attack by the militant group in northern Iraq, the Pentagon said in a statement on Saturday.

It was the second combat death of an American service member in Iraq since the start of the campaign to fight the militant Islamic State group.

The Marine, who was providing force protection fire, died in the rocket attack at a base near Makhmur, a town between the cities of Mosul and Kirkuk, Pentagon Press Secretary Peter Cook said.

Cook did not identify the Marine who had been killed. He said several other Marines had been wounded and were being treated for injuries.
