Ukrainian forces strike the Slavneft-YANOS refinery in Yaroslavl: fire breaks out at the facility

On the night of August 27–28, 2026, the Ukrainian Armed Forces carried out a strike on the Slavneft-YANOS oil refinery in Yaroslavl, Yaroslavl Oblast. This is reported by RBC-Ukraine, citing a summary from the General Staff of the Ukrainian Armed Forces. According to Ukrainian military data, a fire broke out on the facility's territory immediately after the attack.

Course of the attack and aftermath

The General Staff of the Ukrainian Armed Forces emphasizes that the exact scale of the damage is currently being established and will be announced later. Thus, there was no official assessment of the destruction at the time the summary was published. Ukrainian and independent media outlets, citing footage from the scene, record active burning on the enterprise's site.

What is Slavneft-YANOS

According to the defenders' explanation, Slavneft-YANOS is one of Russia's largest oil refineries, part of PAO Slavneft. The plant's capacity is approximately 15 million tons of crude oil per year. The enterprise operates on a full-cycle processing basis and produces a wide range of petroleum products. The Ukrainian side also notes that the plant supplies the needs of the Russian armed forces in the war against Ukraine.

Series of strikes on refineries

The attack in Yaroslavl became part of a whole series of strikes on oil refining infrastructure. Thus, on August 26, following a strike by a Ukrainian drone, the LUKOIL-Nizhnevartovsknefteorgsintez (NORSI) refinery in Kstovo halted crude oil processing. The Afipsky refinery in Krasnodar Krai was also hit, where a unit for the joint processing of gas and gas condensate caught fire. On the night of August 22, drones attacked the Novokuybyshevsk refinery in Samara Oblast.

Contradictory data

On the one hand, the fact of the strike and the fire is confirmed by several outlets — RBC-Ukraine, Svoboda, TVNET and Deutsche Welle. On the other hand, the General Staff of the Ukrainian Armed Forces does not disclose the extent of the damage, and the German outlet DW emphasizes that drones have struck the Yaroslavl refinery for the eighth time in a year. An independent assessment of the enterprise's actual losses and the degree of processing shutdown is currently absent, so claims of the "defeat" of one of the largest refineries remain pending official figures for now.
