A U.S. defense official says a U.S. military operation to rescue Kurdish hostages in northern Iraq resulted in one U.S. fatality.
Details are sketchy in advance of an expected U.S. public announcement. But the official says the mission was carried out overnight in the vicinity of Hawija, west of Kirkuk.
The official spoke on condition of anonymity because the operation had not yet been announced.
