The Ryazan Oil Refinery in Russia has suspended operations due to damage from Ukrainian drone attacks, Reuters reported on Jan. 27, citing two industry sources. Ukraine confirmed hitting the plant in an overnight drone strike on Jan.

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.

Russia launched a barrage of drones in an overnight attack on Ukraine on Friday, killing three civilians and damaging residential and commercial buildings, officials said.
