Ukrainian drones strike Yaroslavl refinery, one of Russia's five largest

Drones attacked the Yaroslavl oil refinery, one of Russia's five largest, on the night of November 3, causing a fire at the facility that supplies fuel for military aviation and equipment. Local residents reported multiple fire sources on the plant's territory. The refinery, owned by Slavneft and jointly controlled by Rosneft and Gazprom Neft, processes about 15 million tons of oil annually. It produces gasoline, diesel, fuel oil, aviation kerosene, and lubricants for central and northwestern Russian regions, including Moscow Oblast, with consumers including airports and military-industrial facilities. The attack is part of a series of Ukrainian strikes on Russian oil infrastructure over the past week, which OSINT analysts estimate has disabled 10% of Russia's refining capacity in three days. Previous targets included refineries in Novokuybyshevsk, Ufa, and Kstovo, with Russian radars reportedly detecting up to 150 drones during the Yaroslavl incident.
