A Ukrainian drone attack last week forced a refinery in Ryazan, southeast of Moscow, to suspend operations. Russia's Defense Ministry said in a statement on Friday that 49 Ukrainian drones had been downed over the country overnight, including 25 in the southern Rostov region and eight in the Volgograd region.

"The Volgograd oil refinery has been hit. It is one of the largest in Russia. Its design capacity is about 14 million tons of oil per year, making it the sixth-largest refinery in Russia. The refinery produces gasoline, diesel fuel, fuel oil, and aviation fuel," Kovalenko said.

On the night of Friday, January 31, the Russian army launched 102 kamikaze drones at Ukraine. Ukrainian air defense forces operated in 12 regions of the country, according to the Air Force of the Armed Forces of Ukraine.
