Saudi Arabia's East-West Pipeline system was hit by projectiles on Sept. 10, CNN reported Sept. 11, citing two U.S. officials. One U.S. official said that the system was struck by drones originating from Iraq. The extent of the damage is unclear, though satellite data taken on Sept. 10 detected nine large fires burning near the pipeline, with six appearing to originate from flare pits used to burn off oil and gas during an emergency.
