Ukrainian Drones Strike Lukoil's Kstovo Refinery, Third Major Hit in Three Days

Ukrainian long-range drones struck the Lukoil-Nizhegorodnefteorgsintez refinery in Kstovo, Nizhny Novgorod Oblast, overnight on 1 November 2026. Fires broke out across the complex, which has a design capacity of about 17 million metric tons of crude per year and ranks among Russia's largest. Governor Gleb Nikitin said air defences destroyed more than 100 drones and that an industrial facility in the Kstovo district sustained significant damage. He did not name the site, but videos circulating on social media showed large fires on the refinery grounds.

The attack also hit the adjacent Novogorkovskaya combined heat and power plant, which supplies steam and electricity to the refinery and surrounding petrochemical facilities. Ukrainian monitoring channels reported multiple impact points. Ukraine's General Staff had not issued a statement by midday. The strike was the third on Russian refining capacity in three days. Drones had earlier hit the Novokuibyshevsk refinery in Samara Oblast and the Bashneft-Novoil plant in Ufa. Together the three facilities process roughly 10 percent of Russia's refining capacity and a similar share of its diesel output.

Kstovo is Lukoil's fourth-largest refinery and one of the country's main producers of motor gasoline. A prolonged shutdown of primary distillation units would reduce available refined products for the domestic market and for export. Russian authorities have not released damage assessments or repair timelines. Previous strikes on Russian energy infrastructure have taken weeks or months to restore full capacity when key processing units are hit.

The timing coincides with the end of a localised ceasefire in Ukraine's Kherson region and with the compromise of both countries' air-alert applications. Ukrainian forces have resumed attacks on Russian energy targets after a brief pause. Russian oil product exports have already faced constraints from earlier strikes and from sanctions. Any further reduction in refining throughput would tighten supplies of gasoline and diesel inside Russia and raise the cost of products that still reach foreign buyers.

Nizhny Novgorod Oblast lies more than 700 kilometres from the Ukrainian border. The ability of drones to reach the site and penetrate local air defences indicates continued Ukrainian capacity for deep strikes. Russian air defence units reported intercepting large numbers of incoming aircraft, yet enough munitions got through to start visible fires. Satellite imagery released in the coming days will show which specific units were damaged.

Local residents reported power fluctuations and heavy smoke. Emergency services worked through the night. No civilian casualties have been confirmed at the Kstovo site. The broader pattern of attacks on refining capacity since late October has forced Russian officials to prioritise repairs at multiple locations simultaneously, stretching specialised repair crews and spare parts.

For Ukraine, the strikes form part of a campaign aimed at reducing the revenue and fuel supplies available to Russian forces. For Russia, each successful hit raises the cost of maintaining both military operations and civilian fuel distribution. The next reports on production levels at Kstovo, Novokuibyshevsk, and Ufa will show how much capacity has been lost and for how long.
