Ukrainian Drone Attack Ignites Large Fire at Ryazan Oil Refinery in Russia
Ukraine's military launched a large-scale retaliatory drone attack overnight on May 15, 2026, striking the Rosneft-owned Ryazan oil refinery. Local residents reported multiple explosions before a massive fire broke out at the facility, which produces over 17 million tons of oil annually. Ryazan Governor Pavlo Malkov confirmed that drone debris also struck residential buildings, resulting in three fatalities and 12 injuries. The attack follows a deadly Russian bombardment of Kyiv the previous day.
