What happened

Ukrainian drones struck the Bashneft-UNPZ refinery in Ufa overnight, hitting the ELOU-AVT-6 primary crude-distillation and desalting unit — a unit with capacity of more than 6 million tonnes a year that separates crude into kerosene, gasoline, diesel and fuel oil for further processing. Acting Ufa mayor Rustam Sharipov said six drones attacked the city, four of which were shot down, with the remaining drone(s) sparking a fire in the industrial zone; Bashkortostan governor Radiy Khabirov confirmed a drone struck a refinery unit undergoing repairs and damaged pipelines. OSINT monitoring (Exilenova+, reviewed by Militarnyi) geolocated the impact to the AVT-6 unit, the same unit Ukrainian forces had already struck on 2 August 2026 — meaning this strike hit the unit again while repair work from the earlier attack was still underway. No casualties were reported. Bashneft-UNPZ is one of three adjoining Ufa-area Bashneft refineries with a combined annual capacity of about 23.5 million tonnes; no Russian official damage assessment or production-halt confirmation specific to this strike was found in the cited reporting, so this record does not assert a shutdown beyond the confirmed unit damage.

When cited sources give different casualty, damage or spill figures for this event, they’re reported side by side above rather than merged into one number. See how confidence levels work.
