Ukrainian drones hit Russia's largest oil refinery in Omsk, 2,500 km from Ukraine

Drones struck Russia's largest oil refinery in Omsk on the evening of November 11, marking a major attack on a key energy facility located about 2,500 kilometers from Ukraine's border. Local residents reported explosions and impacts that shook windows in nearby homes, with the drone attack and blast sounds lasting over two hours. Authorities restricted cellular communications and mobile internet, while air raid sirens sounded and the local airport suspended flights. The Omsk refinery, owned by Kremlin-controlled Gazprom Neft, has a capacity of 22 million tons of oil annually and supplies fuel to the Russian military, producing every sixth liter of Russian gasoline and diesel. Ukrainian drones previously struck the facility on July 6, October 8, and October 24.
