A Russian oil refinery was set ablaze after being struck by suspected Ukrainian drones, the region’s governor said. 

The oil refinery in Ryazan was hit by drones overnight, causing a fire, the Russian Telegram news channel Astra reported. A source told the Kyiv Post the operation was carried out by the Ukrainian military intelligence service. 

Ryazan governor Pavlo Malkov said an “inspection is ongoing” at the site on Tuesday morning. There were no reports of fatalities. 

The US has urged Ukraine to stop striking Russia’s oil and energy infrastructure, warning that the drone attacks risk driving up global oil prices and provoking retaliation.

The refinery, owned and run by Rosneft, refines about 5.8 per cent of Russia’s total refined crude. It has been a frequent target for Ukraine’s air attacks.
