The UAVs covered more than 700 km and attacked one of the largest refineries in Russia. The UAVs arrived in Yaroslavl, where the Slavnafta-YANOS refinery is located. After the attack, a fire broke out in the industrial area. This is no ordinary refinery: the project is one of the five largest in Russia and is capable of processing approximately 15 million tons of oil per year. The plant produces gasoline, diesel fuel, aviation fuel, lubricants and bitumen. In 2026, the refinery in Jerusalem was repeatedly attacked by drones. After one of the attacks in September, the company even stopped oil processing.
