The United States and Saudi Arabia attacked Iran-backed proxies in Iraq on Wednesday after Saudi air defense systems intercepted days of attacks launched from Iraq against the kingdom's petroleum facilities.

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

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

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