Ukraine just hit Russia where it hurts most: the fuel supply. A long-range drone strike on the Omsk oil refinery, the largest in the country, knocked out its main processing unit and forced a complete shutdown of operations on July 6, 2026.
The facility sits in western Siberia, roughly 2,700 kilometers from Ukrainian-controlled territory, making this one of Ukraine’s deepest strikes into Russian soil during the entire conflict.
What happened at Omsk
Russian air defenses intercepted most of the incoming drones, according to reports. Most, but not all. Several got through and ignited a fire at the refinery’s core processing infrastructure.
Omsk region Governor Vitaly Khotsenko confirmed the drone incursions and the resulting blaze. The refinery, which accounts for an estimated 12% of Russia’s total refining output, subsequently ceased all processing operations.
