<h1>Drones Strike Major Oil Refinery Producing 17.7 Million Tonnes Annually; Explosions, Fire Extinguished, No Injuries</h1> Drones launched by one state struck a major oil refinery in the northwestern Leningrad region overnight, causing explosions and a fire that was subsequently extinguished; local authorities reported drones were intercepted and no injuries occurred. The targeted facility produces roughly 17.7 million tonnes of crude annually. The attack follows a series of similar assaults on fuel infrastructure by the same attacker, which the target attributes to efforts to disrupt its war-sustaining supplies. The strikes have contributed to domestic gasoline shortages, prompting the target to impose temporary export restrictions and rationing measures.
