The Pentagon has identified the American killed in Iraq on Thursday as a 34-year-old Navy chief petty officer named Jason C. Finan.
The Pentagon said Finan's hometown is Anaheim and that he was assigned to Explosive Ordnance Disposal Mobile Unit Three.
He died of wounds sustained in a roadside bomb attack north of Mosul. He was part of a U.S. team advising and assisting Iraqi Kurd fighters known as peshmerga.
Finan is the fourth U.S. combat death in Iraq since U.S. military operations against the Islamic State began in Iraq in August 2014.
