A US Marine was killed in northern Iraq on Saturday, according to a Combined Joint Task Force-Operation Inherent Resolve report.
The service member was providing force protection fire support at a base in Makhmur when troops came under ISIS (also known as Islamic State, ISIL) rocket fire.
Makhmur is approximately 45 miles southeast of ISIS-held Mosul.
"Several other Marines were wounded and they are being treated for their varying injuries," according to a statement from Pentagon Press Secretary Peter Cook.
"Our thoughts and prayers are with the service members involved, their families and their coalition teammates who will continue the fight against ISIL with resolved and determination," Cook wrote.
The identity and nationality of the service member will not been released until the family is notified.
To date, Operation Inherent Resolve has conducted 10,962 strikes, with 7,336 in Iraq and 3,626 in Syria.
Master Sergeant Joshua Wheeler, 39, of Roland, Oklahoma, became the first American to die in combat operations against ISIS, Reuters reports.
He was killed during an overnight October 2015, mission to rescue hostages held by ISIS militants.
Wheeler is survived by his wife and four sons.
