US military official confirms 'self-defense strike' in Iraq

A "self-defense strike" was carried out in northern Iraq against a drone launch site, a U.S. military official said, after an air strike killed five pro-Iranian militants there.
"A self-defense strike was carried out on a drone staging site," the official said on condition of anonymity. It took place "in the vicinity of Kirkuk" and targeted "an imminent threat", he added.
