Ukrainian drones reportedly struck a military-industrial facility in Sterlitamak, located in Russia’s Bashkortostan Republic, more than 1,300 kilometers from Ukraine, according to social media reports on September 4, 2026. The Sterlitamak Petrochemical Plant, which supplies aviation fuel and other materials to Russia's defense industry, was identified as the target. Bashkortostan authorities confirmed a drone attack on the city's industrial zone but did not immediately specify the facility.

The plant has been a repeated target for Ukrainian long-range drones, with previous strikes occurring in November 2025 and April 2026. Drones also attacked Sterlitamak's industrial zone on August 27. Ukraine's strategy of targeting oil and gas processing facilities in Russia aims to disrupt fuel supplies for both civilian and military use, and to cut off a significant source of funding for Russia's ongoing military operations. The Sterlitamak Petrochemical Plant, which began operations in 1963 during the Soviet era, is owned by Russian chemical holding company Ruschem, formerly known as Russian Hydrogen.
