Videos showed fireballs over a facility in Ryazan, 110 miles southeast of Moscow. Kyiv is seeking to disrupt Russian military logistics and put pressure on the country’s economy by striking its oil industry.

The reported strike comes two nights after Ukrainian forces launched a joint attack against the refinery that allegedly damaged multiple on-site facilities.

The General Staff of Ukraine's Armed Forces confirmed an attack overnight that hit Russia's Ryazan Oil Refinery and the Ryazan Thermal Power Plant, leaving them ablaze Thursday morning.

Ukrainian drones hit a Russian oil refinery in the city of Ryazan overnight, causing a fire and damaging equipment at one of Russia's biggest refineries, four industry sources told Reuters on Friday.

Russia says it shot down more than 120 drones overnight, in what would be one of the largest attacks of the war.
