Ukraine attacks petrochemical plant in Bashkortostan with drones, says Russia

“A Ukrainian drone attack damaged the Sterlitamak petrochemical plant deep inside Russia, causing a partial collapse of a water-treatment facility but no injuries,” regional authorities said on Tuesday (November 4, 2025).

“The plant in the Bashkortostan region, some 1,500 km from the Ukrainian border in the Urals Mountains, was operating without interruption,” the head of the Bashkortostan region, Radiy Khabirov, said on the Telegram messaging app.

Mr. Khabirov added that both of the drones involved in the overnight strike were destroyed. The Russian Defence Ministry said in its daily report that in addition to the two drones downed over the Bashkortostan region, its defence systems destroyed 83 drones over seven other Russian regions.

The administration of the city of Sterlitamak, where the plant is located, said that all five workers inside were not injured.

There was no immediate comment from Ukraine. Kyiv has stepped up long-range drone and missile strikes inside Russia, hitting oil refineries, depots, and logistics hubs, which it says feed the Kremlin’s war machine.

Moscow calls the attacks terrorism, but Ukraine says they are legitimate self-defence in the war that Russia launched in February 2022.
