A Ukrainian drone strike ignited a fire at the Tyumen oil refinery in western Siberia on Saturday, July 25, underscoring the increasing reach of Kyiv's long-range drone campaigns against Russian energy infrastructure. The facility is located more than 2,000 km from Ukraine.
Regional governor Alexander Moor confirmed the incident, stating that emergency services were dispatched to the scene. Local residents reported hearing at least two explosions and observing smoke over the refinery, with some noting activity from the refinery's flare system.
The Tyumen Oil Refinery, a branch of the Moscow-based company Ri-invest, is the only large refinery in the Ural Federal District and one of Russia's largest independent refineries. It has a nominal capacity of around 8 million metric tons per year, processing roughly 6 million tons of crude annually to produce gasoline and diesel fuel. The refinery was previously known as the Antipinsky Refinery and was acquired by Ri-invest in May 2021 following bankruptcy.
This attack is part of a broader pattern of Ukrainian strikes targeting Russian energy and military infrastructure. The refinery had previously been targeted by drone strikes on June 20, 2026, and in October 2025. Any disruption to its output could further strain Russia's domestic fuel market, which has experienced worsening shortages.
