Ukraine Says It Struck Lukoil’s Kstovo Refinery; Local Footage Shows Large Fire

Ukraine’s General Staff said its forces struck one of Russia’s largest oil refineries overnight, targeting Lukoil’s refinery in Kstovo in the Nizhny Novgorod region. Multiple videos and photos circulated locally and were cited by Ukrainian and international media as showing a large fire at the site, with flames, smoke and apparent explosions visible in the refinery area. As of Wednesday morning, however, the full extent of the damage had not been independently confirmed by Lukoil or Russian authorities.

In a statement, the General Staff of the Armed Forces of Ukraine said Ukrainian forces hit facilities at the Lukoil-Nizhegorodnefteorgsintez plant during the night of Aug. 26 and that a fire broke out on the refinery grounds. The military said the scale of the damage was still being clarified. The images and footage that emerged overnight support that a significant fire took place in the Kstovo refinery area, but they do not by themselves establish what weapon was used, the exact point of impact, or how badly the plant was damaged. At the time of reporting, Lukoil had not issued a same-day public statement on the incident, and there was no clearly attributable statement from Russian regional or federal authorities detailing the damage or any effect on operations.

The refinery’s importance helps explain why the reported strike matters. The Kstovo plant, also known as NORSI, is part of the Lukoil group and has a stated processing capacity of about 17 million tonnes of oil per year, making it one of Russia’s biggest refineries. It produces gasoline, diesel, aviation fuel, fuel oil, bitumen, sulfur and other petroleum products. Ukraine’s military said the refinery supports the needs of the Russian armed forces, though that specific role has not been independently verified in the reporting available Wednesday morning.

The overnight attack was also not the first time the Kstovo refinery had reportedly come under attack this year. Earlier reporting cited strikes on the site in May and again in July 2026. That places the latest incident within a broader pattern of repeated Ukrainian long-range strikes on Russian energy and logistics infrastructure, though the immediate facts of this case remain limited to Ukraine’s statement and the visual evidence of a fire.

What remains unclear is central to assessing the significance of the strike. There was no independent confirmation by Wednesday morning of how much of the refinery was damaged, whether key processing units were affected, or whether the plant’s operations were disrupted. There was also no public same-day accounting from Lukoil or a detailed official Russian statement describing what happened at the site. For now, the verified core is narrower: Ukraine says it struck the Kstovo refinery overnight, and local footage indicates that a major fire followed.
