What happened

Ukraine's General Staff confirmed that its Defense Forces struck the Bashneft-UNPZ oil refinery in Ufa, Republic of Bashkortostan, on the night of 21-22 September 2026, saying a fire was reported on the facility's premises. The strike came in the same wave as a separate, confirmed hit on the Kuibyshev refinery in Samara (see the linked 22 September 2026 Kuibyshev record). Ukraine's Center for the Study of Occupation had earlier described preliminary, unconfirmed reports that 'one of the Bashneft refineries' in Ufa was targeted, and Ufa International Airport briefly restricted operations during the attack. No casualties were reported at the refinery. No source reviewed named the specific unit struck, confirmed a production halt, or gave a restoration timeline; the General Staff's confirmation covers the strike and reported fire, not a verified damage assessment. This is a distinct repeat-strike entry for the same Bashneft-UNPZ facility as the documented 2 August and 19 August 2026 attacks.
