Ukrainian drones hit an industrial site in Tyumen region in Western Siberia, sparking a fire. Ukrainian OSINT monitors identify the target as the Tyumen oil refinery—the former Antipinsky plant—which was also hit in June and late July. The refinery sits more than 2,000 km from the Ukrainian border, deep in Western Siberia. It's one of Russia's larger independent refineries, with capacity of around 7.5–9 million tonnes per year, mainly supplying Western Siberia and the Urals with gasoline and diesel.
