"Warning. The area is under a hostile aerial threat. Please remain calm, stay indoors or in a safe place away from windows and doors, and follow the instructions of Civil Defence," the message said, before lifting the warning minutes later.

Saudi Arabia has faced near-daily strikes since October, when the Houthis intensified their campaign against the kingdom after ousting Riyadh-backed government forces from their positions on the Red Sea coast.
