Yemen's Iran-backed Houthis claimed responsibility for a drone attack on Saudi Aramco's $21 billion Jazan refinery, located on Saudi Arabia's southwestern Red Sea coast, roughly 44 miles from the Yemeni border. The facility is strategically important because it allows Aramco to export refined products through the Red Sea without transiting the Strait of Hormuz. The attack also signals the growing vulnerability of Saudi energy assets in the region, where Houthi forces have repeatedly targeted them in recent weeks.

A Bloomberg report cites Saudi Arabia's Energy Ministry, which said a fire broke out early Sunday at the 400,000-barrel-a-day Jazan refinery before being extinguished.
