Ukraine Struck Rosneft-Operated Refinery in Russia’s Samara Region

Ukraine has claimed responsibility for a drone strike targeting a Rosneft-operated oil refinery in Russia’s Samara region, marking the latest in a string of attacks on energy infrastructure deep inside Russian territory, according to a statement from Ukraine’s General Staff.

In a post on Telegram, Ukrainian military officials said the Novokuybyshevsk refinery was hit overnight, reporting explosions and a resulting fire at the site. No additional details were provided regarding the scale of the damage or the operational impact on the facility.

The claims could not be independently verified. Rosneft has not responded to requests for comment sent outside business hours on Sunday.

Ukraine also issued an update on a separate strike it reported a day earlier on Russia’s large Ryazan refinery, saying two key crude-processing units were damaged along with a petroleum storage tank and a pipeline bridge. The facility is one of the major refining hubs feeding Russia’s domestic fuel network.

Russian officials have not publicly confirmed the extent of the damage. The governor of Ryazan region said only that drone debris had fallen on an unspecified industrial site.

Samara regional governor Vyacheslav Fedorishchev said on the VKontakte social network that the area—located around 1,300 kilometers northeast of Kyiv, had come under attack by Ukrainian drones overnight. He did not specify whether the Novokuybyshevsk refinery was impacted.

The refinery, which has a processing capacity of around 170,000 barrels per day, had previously been targeted in August, part of Ukraine’s expanding long-range drone campaign aimed at disrupting Russia’s fuel production.

The latest incidents highlight Ukraine’s continued strategy of hitting Russian refineries and energy infrastructure far from the front lines, an approach intended to strain Moscow’s wartime logistics and economic stability. Recent months have seen several such strikes reach as far as central Russia, underscoring Kyiv’s growing long-range drone capabilities.
