An air strike Sunday killed at least five pro-Iranian militants in Iraq’s northern Kirkuk province, two Iraqi security sources told AFP. The raid targeted a site used by an armed group affiliated with Hashed al-Shaabi, a coalition of former paramilitary forces integrated into the Iraqi regular military, a senior security official in Kirkuk said without saying who had launched the attack. It came a day after the government in Baghdad had warned the United States against “attacks” on Iraqi territory.
