A senior Saudi official told Reuters that Iranian-backed Iraqi militias and Yemen's Houthis are coordinating to execute imminent strikes against Saudi Arabia. The official said that potential targets include economic infrastructure, such as energy facilities, ports and airports, with Saudi Arabia observing drone and missile movement.

The warning comes as Saudi Crown Prince Mohammed bin Salman, Pakistani Prime Minister Shehbaz Sharif, and Turkish President Recep Tayyip Erdogan are scheduled to hold a summit tomorrow in Jeddah, according to AFP. An official agenda has not been released.
