Ukrainian drones struck Russia’s Syzran oil refinery early morning on Thursday, May 21, sparking a massive fire at one of Rosneft’s major fuel-processing facilities as Kyiv’s long-range campaign against Moscow’s energy infrastructure intensifies. Governor Vyacheslav Fedorishchev confirmed the strike on the city of Syzran in Russia’s Samara region, claiming two people were killed and several others injured.JOIN US ON TELEGRAMFollow our coverage of the war on the @Kyivpost_official. Russian officials blamed “enemy” drone attacks, while local footage shared online showed towering flames and thick black smoke engulfing the refinery complex. According to Russian independent outlet Astra and Ukrainian monitoring channel Exilenova+, the target was the Syzran refinery, which processes up to 8.5 million tons of oil annually. The latest strike marks the second attack on the facility in just over a month. On April 18, Ukrainian drones reportedly damaged critical technological equipment at the plant, forcing the shutdown of the AVT-6 primary refining unit – responsible for more than 70% of the refinery’s processing capacity. The attack is part of Ukraine’s broader strategy to degrade Russia’s military logistics and fuel supplies by targeting the country’s sprawling oil infrastructure deep behind the front lines. Over recent weeks, Ukrainian drone strikes have disrupted operations at major refineries across central Russia, including facilities in Moscow, Nizhny Novgorod, Ryazan, and Yaroslavl, according to Reuters.
