Ukraine said it targeted one of Russia’s largest oil refineries overnight, hitting the Ryazan facility operated by state-owned Rosneft, while Moscow simultaneously carried out one of its broadest assaults in months on Ukraine’s power infrastructure.
In a statement on Telegram, Ukraine’s military reported that its forces struck the Ryazan refinery, located about 193 kilometers (120 miles) southeast of Moscow, during the night. The refinery, with a design capacity of around 340,000 barrels per day, is among the largest in Russia and has been attacked multiple times in recent months.
The claims could not be independently verified. Rosneft did not respond to an after-hours request for comment on Saturday.
The strike comes on the heels of a wave of Ukrainian drone attacks on Russian refineries throughout November. Another Rosneft refinery, located in Syzran, was also hit on Friday.
Kyiv has increasingly focused on disrupting Russia’s fuel supply chain in an effort to undermine Moscow’s military operations. The attacks coincide with continued diplomatic efforts toward a negotiated peace, though no significant breakthroughs have emerged.
Russia launched an extensive barrage on Ukraine’s energy network overnight, deploying 653 drones and 51 missiles, according to Ukraine’s General Staff.
The assault triggered widespread power outages across several regions, including Odesa, Chernihiv, Kyiv, Kharkiv, Dnipropetrovsk, Zaporizhzhia, and Mykolaiv. The Ministry of Energy said that numerous facilities had been damaged, while DTEK, Ukraine’s largest private energy company, confirmed that equipment at one of its thermal power plants had been hit.
The International Atomic Energy Agency said on X that the scale of military activity forced several of Ukraine’s operating nuclear plants to reduce output as the national grid came under severe pressure.
