**Deck**: Ukrainian drones attacked Russia’s Kstovo oil refinery in Nizhny Novgorod region, triggering several fires at a major fuel facility about 250 miles east of Moscow. The strike shows Kyiv’s drone campaign reaching deeper into Russian territory and putting industrial sites under new pressure.

A Ukrainian drone strike on Russia’s Kstovo oil refinery has set off several fires at a key fuel facility far from the front line, according to reports from both Ukrainian and international channels.

A brief update from pro-Ukrainian sources stated that Ukrainian drones attacked the Kstovo oil refinery in Russia’s Nizhny Novgorod region during the night, causing multiple fires. Another report, shared by a global news feed, said there was a fire at a refinery in the Nizhny Novgorod area about 250 miles east of Moscow and noted that the site had been attacked. The description and location indicate these reports refer to the same facility.

The information available so far doesn’t include confirmed details on casualties, how large the fires were, or how long operations at the refinery might be disrupted. Even so, a blaze at a refinery this far inside Russia highlights Ukraine’s ability to send drones deep into Russian airspace and reach industrial targets previously considered out of easy range.

Operationally, a refinery in Nizhny Novgorod helps supply fuel to nearby regions and the wider domestic market. Any damage that forces a slowdown or temporary shutdown would require Russian planners to adjust fuel logistics, drawing more heavily on other facilities and transport routes. For refinery staff and nearby residents, nighttime explosions and visible fires reinforce the sense that industrial sites have become part of the war zone, despite being hundreds of miles from Ukraine.

The strike also fits a pattern of Ukrainian attacks on oil and energy infrastructure inside Russia, from depots near the border to refineries deeper inland. Each successful hit demonstrates both the reach of Ukrainian drones and the challenge facing Russian air defenses in protecting wide networks of critical infrastructure.

Key developments to watch now are Russian statements clarifying the scale of the damage and repair timelines at the Kstovo plant, any visible changes in air-defense deployments around refineries in Nizhny Novgorod and other regions, and signs of follow-on Ukrainian drone activity against similar sites.
