Ukrainian forces struck production facilities at the Novokuybyshevsk oil refinery in Russia’s Samara Oblast overnight on 22 August, sparking a fire at the Rosneft-owned plant, Ukraine’s General Staff said. The extent of the damage remains under assessment.

Ukraine has repeatedly targeted Russia’s oil refineries to restrict military fuel supplies and reduce the energy revenues supporting Moscow’s war. The latest strike came as gasoline rationing returned to Moscow and St. Petersburg, and Rosneft capped nationwide purchases. Militarnyi described the plant as one of Russia’s 10 largest refineries.

The Rosneft-owned refinery can process about 8.8 million metric tons of crude annually and produces more than 20 petroleum products, including aviation fuel and diesel, Ukraine’s General Staff said.

Fire Point said FP-1 long-range drones were used to strike the refinery.

The same overnight wave also hit an Ozon logistics center in Chapayevsk, where people were injured, and work was halted, Reuters reported, citing the company.

Neither the damage to the refinery nor any interruption to production has been independently confirmed.

Ukraine keeps pressure on Russian fuel supplies

The strike came one day after Ukraine confirmed hitting Lukoil’s Perm refinery, approximately 1,530 kilometers from Ukraine’s northern border. That attack also caused a fire, according to the General Staff.

At least four Russian refineries went offline during August amid continuing Ukrainian attacks.

By mid-August, filling stations in at least 12 Russian regions were experiencing hours-long lines. Some areas had reintroduced purchase limits or rationing based on license-plate numbers, according to the same report.

Gasoline limits had also been reinstated in Moscow and St. Petersburg, while Rosneft had capped sales at 30 liters per vehicle across its nationwide filling-station network. Diesel purchases remained unrestricted.
