WASHINGTON — The United States carried out three airstrikes early Monday morning in Iraq and Syria against weapons storage facilities used by Iranian-backed militias that in recent weeks have conducted armed drone strikes against locations where the American military is, the Pentagon said on Sunday. …
The United States is grappling with a rapidly evolving threat from Iranian proxies in Iraq after militia forces specialized in operating more sophisticated weaponry, including armed drones, have hit some of the most sensitive American targets in attacks that evaded U.S. defenses.
At least five times since April, those militias have used small, explosive-laden drones that divebomb and crash into their targets in late-night attacks on Iraqi bases — including those used by the C.I.A. and U.S. Special Operations units, according to American officials.
