Ukrainian forces have struck the Omsk oil refinery in western Siberia, the deepest strike inside Russia since the war began, temporarily halting operations at the country's largest processing facility.
The drone attack, announced by Ukraine's military on Sunday, targeted a site roughly 2,700 kilometres from Ukrainian territory. Omsk Governor Vitaly Khotsenko confirmed the strike, saying air defences downed most drones with no casualties reported. Ukrainian special forces said the primary ELOU-AVT-11 processing unit was damaged, while other installations were shut down due to pipeline damage. The refinery, owned by Gazprom Neft, suspended wholesale fuel sales and was temporarily shut down.
Videos circulating on social media showed flames at the complex, which processes over 21 million tonnes annually and supplies fuel to the Russian military. President Volodymyr Zelenskyy called the strike "a major blow to Russia's oil economy." The attack has added to existing fuel shortages in Russia.
