Drone attacks claimed by Yemen's Houthi rebels set alight two major oil facilities run by the state-owned company Aramco in Saudi Arabia on Saturday, the Kingdom's Interior Ministry said.

The Saudi Press Agency, citing a statement by the Ministry, said that the drones caused the fire at the refinery in the city of Abqaiq in the Kingdom's oil-rich Eastern Province, as well as the blaze at the Khurais oil field, around 150 km from Riyadh. Abqaiq is the location of the world's largest oil processing plant, which handles two-thirds of Saudi oil production. Khurais contains the country's second-largest oilfield.
