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

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.

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.

Ukraine drones hit an oil refinery east of Moscow in a mass attack on Russia, according to military sources. The oil plant in Ryazan, 120 miles south east of the capital, was targeted, as was a microelectronics production plant in Bryansk, western Russia, according to Ukraine’s military.
