An early-Tuesday attack near Ras Tanura on Saudi Arabia's Persian Gulf coast sparked a fire that Saudi authorities say is now under control; damage remains unclear, a source said. Ras Tanura contains key export infrastructure, Saudi's largest refinery and extensive tank farms. In recent weeks Houthi forces have struck multiple Saudi energy targets, including ARAMCO headquarters, a major oilfield and a western refinery. Saudi air defenses said they intercepted and destroyed three ballistic missiles fired toward the east; the Saudi-led coalition reported intercepting four drones and three missiles.
