Today, Friday, a drone attack targeted an oil refinery in the Saudi capital, which was caused by a small fire, in light of soaring crude prices. 

The attack took place in the early hours of Thursday morning.

"The Riyadh oil refinery was attacked by a drone, resulting in a small fire that has been brought under control," the Energy Ministry said, according to the official Saudi Press Agency.

"The attack did not result in any injury or death, nor was the supply of oil or its derivatives affected."

Brent oil prices have varied between $139 and $105 in extreme volatility this week after the anti-Russian sanctions campaign caused a global energy crisis. 

Saudi Arabia, one of the world's largest oil exporters, and its partners in the OPEC alliance have been pressured to increase supply to rein in prices. 

State media reported today, Friday, that Saudi Arabia's Riyadh refinery was attacked by a drone, but no injuries were reported and no oil supply components were damaged.
