Ukraine strikes Russian petrochemical plant in Siberia over 2,000 kilometers from border

Ukrainian long-range drones struck the Tobolskneftekhim petrochemical plant in Tobolsk, western Siberia, on August 10, 2026. Located over 2,000 kilometers from the border, the strike damaged the central gas fractionation unit, which processes 6.6 million tons of feedstock annually for rocket fuel, aviation fuel, and drone composites. President Volodymyr Zelensky praised the operation as a major milestone proving Siberia is no longer a secure rear. The attack forced an indefinite shutdown of the plant and occurred alongside another strike on the Taneco refinery in Tatarstan.
