Ukrainian drones strike one of Russia's top oil refineries, sparking fire

Ukrainian drones overnight struck one of Russia’s largest oil refineries, sparking a fire, according to Russian officials and Ukraine’s military. The strike on the Kirishi refinery, in Russia's northwestern Leningrad region, follows weeks of Ukrainian attacks on Russian oil infrastructure that Kyiv says fuels Moscow’s war effort. The facility, operated by Russian oil major Surgutneftegas, produces close to 17.7 million metric tons per year (355,000 barrels per day) of crude, and is one of Russia's top three by output.
