Two major industrial fires erupted in Russia on 7 June, with blazes at facilities in Kstovo and Pushkino, prompting large-scale emergency responses and raising questions about the causes of the incidents.
In Kstovo, located in Russia’s Nizhny Novgorod Oblast, a bitumen production plant with a capacity of about 200 cubic meters caught fire, according to local emergency services. The facility is situated near the Lukoil oil refinery, one of Russia’s ten largest petroleum processing plants by design capacity.
The area of the fire reached 20,000 square meters, there is a threat of new explosions. Emergency services deployed over 100 rescuers and approximately 35 units of equipment, including a fire train, to combat the blaze.
The Russian Emergency Ministry confirmed that gas cylinders exploded during the incident. Large bitumen storage tanks were burning, with the substance spreading across approximately 100 square meters, according to official statements.
Social media users initially suggested the fire resulted from a drone attack. However, Regional government press services later stated that the fire could have started due to safety violations. No casualties have been reported from the Kstovo incident as of 17:00 local time.
A fuel and lubricants warehouse also caught fire in Pushkino, a town in the Moscow Oblast. Over 50 rescuers and 12 vehicles are involved in firefighting efforts, according to emergency reports.
Russian media outlet Mash reported that the Pushkino facility contained flammable liquids stored in barrels, gas cylinders, and pallets. The fire area initially covered 8,100 square meters but expanded significantly throughout the day.
Both incidents occurred amid ongoing tensions, with the Kstovo Oblast having experienced previous attacks earlier in 2025. In January, Ukrainian intelligence reportedly struck a Lukoil oil depot in the same town, and a Sibur petrochemical plant in Kstovo suspended shipments following what the company described as a Ukrainian drone strike.
The Lukoil refinery in Kstovo processes petroleum products that support Russian military operations, making it a strategically significant facility. The refinery has a processing capacity of 17 million tons annually and is located approximately 800 kilometers from the Ukrainian border.
