In the town of Ryazan, about 200 kilometers southeast of Moscow, strikes were reported on the city’s refinery, one the country’s biggest. Photos and videos posted online appeared to show thick smoke rising from the Ryazan oil refinery, which has an annual capacity of over 17 million tons. As a key factor in powering Russia’s war machine, the Ryazan facility has been targeted multiple times by Ukraine in the past. Also in Ryazan, three civilians were reported killed after drones hit residential buildings. “To our great regret, three people have been killed and 12 injured, including children," Regional Governor Pavel Malkov posted on the Telegram messaging app on Friday morning. Other telegram channels showed pictures of damaged high-rise residential buildings with one saying residents were trapped inside one burning building by a collapsed entrance. Strikes across Russia Telegram users also reported strikes in multiple regions across Russia, including on military and energy infrastructure. Among the military sites reported to have been struck was an airfield in the southern port town of Yeysk. In addition, the mayor of Moscow, Sergiy Sobyani, said five Ukrainian drones were downed before they reached the capital shortly before midnight on Thursday. Two Moscow airports were temporarily closed during the overnight assault. Russia’s defense ministry said 355 Ukrainian drones were intercepted over the country during the night. Explosions were also reported in occupied Crimea. The attacks came a day after Russia launched over 1,500 drones and dozens of missiles at Ukrainian targets, killing at least 21 people and injuring dozens. Among the casualties were people trapped under the rubble of a collapsed residential building in Kyiv. Following the two days of some of Russia’s heaviest bombardments of Ukraine during the four-year war, President Volodymyr Zelenskyy vowed a “just response” saying that Russia must “feel the consequences of their evil.”
