The refinery, owned by Rosneft, was damaged in a drone attack on Aug. 10. It is the third Russian refinery this month to suspend production due to Ukrainian strikes.

Drones attacked an oil refinery on the night of 9-10 August in the Russian city of Saratov, Saratov Oblast, after which a large-scale fire broke out at the facility. There are also reports of air defence activity and explosions in a number of other Russian regions.

The statement said drone strikes caused explosions and a fire on the facility’s grounds. According to the General Staff, the Saratov oil refinery is one of Russia’s key fuel infrastructure sites supplying petroleum products to occupation forces.
