As of June 29, 2026, Ukrainian drones had not attacked only two of Russia’s largest oil-processing enterprises by throughput: the Omsk Refinery in Omsk and the Angarsk Petrochemical Company in the Irkutsk region. Both facilities are located beyond the Urals.
According to Reuters, by the end of May 2026 there was no major refinery left in European Russia that had not been attacked at least once by Ukrainian drones. Some plants were struck several times and then reduced output or halted production altogether.
Against that backdrop, Meduza writes, Russia is facing a large-scale fuel crisis. In the Omsk region, sales of fuel in canisters have been banned, and gas stations are limited to 40 liters of gasoline per customer. In the Irkutsk region, a state of heightened readiness was introduced in June because of the gasoline shortage.
Which major refineries have already been attacked
The list includes Bashneft-Ufaneftekhim in Ufa, Kirishinefteorgsintez in the Leningrad region, Lukoil plants in Volgograd, the Nizhny Novgorod region, and Perm, as well as the Moscow, Ryazan, Tuapse, Tyumen, and Novokuibyshevsk refineries. TANECO, TAIF-NK, and Slavneft-YANOS have also been hit.
At the same time, the outlet says that in June 2025 Ukrainian forces, as part of Operation Web, attacked a military airfield in the Irkutsk region with drones, but there has been no information about other strikes in that region. In the Omsk region, a drone alert was declared for the first time since the start of the full-scale war on June 10, though no downed drones or strikes on specific targets were reported.
Meduza also notes that Ukrainian drones have not reached refineries in the Far East and Eastern Siberia. However, the capacities of those plants are insufficient to fully meet fuel demand across their regions.
