WASHINGTON: The Pentagon on Thursday confirmed that the United States had carried out strikes against five Iran-backed militia weapons storage facilities in Iraq, a day after a deadly rocket attack killed two American and one British service member. “The United States conducted defensive precision strikes against Kataib Hezbollah facilities across Iraq,” a Pentagon statement said. “These weapons storage facilities include facilities that housed weapons used to target US and coalition troops,” it said. The strikes were “defensive, proportional and in direct response to the threat posed by Iranian-backed Shia militia groups,” the statement added.
