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.

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.
