The U.S. Embassy in Saudi Arabia has issued a security alert warning of an imminent missile or drone attack over the eastern city of Dhahran. There is a U.S. consulate in the city, where the headquarters of the Saudi state oil giant Aramco are also located. Iranian drones hit the U.S. embassy in Riyadh earlier on Tuesday, causing minor damage and starting a fire.
The U.S. mission in Kuwait had previously been struck. Washington responded by shutting those missions and ordering non-emergency government personnel and their families to leave countries across the Middle East.
