The U.S. and Saudi militaries announced airstrikes late Tuesday on Iranian-backed groups in Iraq, after Iran and its proxies allegedly targeted American forces.

Iran-backed militants in Iraq recently launched over two dozen drone attacks on US forces and Saudi energy infrastructure.

Attacks come as Saudi Arabia intercepts drones and Iran warns of 'any action' to maintain its control of Hormuz.

U.S. and Saudi air forces struck Iran-backed proxy militias in Iraq, the first announced joint flight and first Saudi attack on Iraq.
