Drone attack sparks explosions and reported fire at Ufa refinery
Drone strikes triggered explosions in Ufa's industrial zone in Bashkortostan overnight on October 31, with a fire reported at the Bashneft-Noyol refinery. The precise target, number of fire sites and extent of damage remain unconfirmed. The attack followed Ukrainian strikes on refining and military-industrial facilities in Samara and Bryansk oblasts.
Key points
- Explosions were reported in Ufa's industrial zone overnight on October 31, 2026.
- A fire was reported at the Bashneft-Noyol refinery, but its location and extent were not independently confirmed.
- Monitoring reports varied between one and three fire sites and identified either Bashneft-Noyol, Bashneft-UNPZ or two refineries as the target.
- Bashneft-Noyol, Bashneft-UNPZ and Bashneft-Ufaneftekhim have a combined refining capacity of 23.5 million tonnes per year.
- Russian authorities said 433 Ukrainian aircraft-type drones were intercepted and destroyed over Bashkortostan and 18 other regions.
- Aviation restrictions were imposed in Ufa, Kazan and Samara.
- The strike followed attacks on the Novokuybyshevsk refinery in Samara Oblast and a military canned-food plant in Bryansk Oblast on October 30.
Why it matters
The reported strike extends Ukraine's campaign against Russian oil-refining and military-industrial facilities. Ufa's three refineries have a combined capacity of 23.5 million tonnes per year, and a fire potentially affecting the L-35 catalytic reforming unit could disrupt fuel production. Aviation restrictions in Ufa, Kazan and Samara also indicate disruption to regional transport operations.
What happened
Drone attacks on Ufa in Bashkortostan triggered explosions in the city's industrial zone overnight on October 31. Local residents reported attacks, and a fire was reported at the Bashneft-Noyol refinery. Russian authorities reported that 433 Ukrainian aircraft-type drones were intercepted and destroyed over Bashkortostan and 18 other regions overnight, while aviation restrictions were imposed in Ufa, Kazan and Samara.
The incident followed Ukrainian strikes on the Novokuybyshevsk oil refinery in Samara Oblast and a military canned-food plant in Bryansk Oblast on October 30. Russian officials said the Bryansk attacks killed two people and injured eight.
How Ukrainian sources describe it
Ukrainian media focus on the confirmed explosions in Ufa's industrial zone while identifying the reported refinery target as either Bashneft-Noyol or Bashneft-UNPZ. Their coverage places the attack within a broader campaign against Russian refining and military-industrial facilities, while emphasizing that the exact target, fire locations and possible damage to the L-35 installation have not been independently confirmed.
Where reporting differs
Ukrainian monitoring outlets and local residents disagree over which Ufa refinery was struck. Some reports identify Bashneft-UNPZ, analysis of witness video points to Bashneft-Noyol, and others suggest two refineries were attacked. Accounts also vary between three separate fire sites and a single fire at Bashneft-Noyol. The claim that the L-35 installation was burning is an inference from photographs rather than an independently confirmed finding. Neither Ukrainian military authorities nor Ufa's local administration confirmed a strike on the refinery.
Background
Bashneft-Noyol has an annual refining capacity of 7.3 million tonnes and produces Euro-6 gasoline, diesel fuel, aviation kerosene and industrial oils. Bashneft-UNPZ has a capacity of about 6.6 million tonnes per year and produces gasoline, diesel fuel, fuel oil and technical sulfur. The L-35 catalytic reforming unit produces high-octane gasoline components and hydrogen used for fuel purification.
Ukrainian forces reported striking Bashneft-UNPZ on September 22 and two refineries in Ufa on June 25. On October 8, they struck the Gazprom Neftekhim Salavat refining complex in Bashkortostan, about 1,300 kilometers from Ukraine's border, and a fire reportedly followed. Explosions and a drone attack were also reported in Sterlitamak on October 29, with smoke near the Bashkir Soda Company, described as Russia's sole producer of a component used in protective materials for armored vehicles. According to the supplied reports, Ukrainian forces carried out at least 73 attacks on 28 Russian oil-product manufacturers in 2025, affecting facilities representing about two-thirds of Russian refining capacity.
