Ukraine begins to destroy metallurgic enterprises inside Russia after oil refineries. New details have emerged of the Ukrainian drone attack on the Mikhailovsky mining and processing plant named after Varicev in the Kursk region according to Charter 97 media outlet. This plant supplied raw materials to the Ural Steel Company, which in turn was a supplier to the armoured vehicle manufacturer Ural Vagan Zavod. This event confirms that after a series of attacks on oil refineries, Ukraine is targeting metallurgic enterprises. The agency writes, the first drone hit a fuel tank and a fire started, the company said. The Mikhailovsky mining and processing noted that there were no casualties. Tass writes, when doctors and firefighters arrived at the plant, the plant was attacked by a second UAV Wright's mash. Governor Roman Starovoyt said that no one was injured in the second attack either. Mikhailovsky mining and processing is one of the largest iron ore mining and processing enterprises in Russia. It belongs to Metaloinvest Company of Alisha Usmanov. In 2019, Metaloinvest published a release stating that the mining and processing plant produced a batch of iron ore pellets to the Ural Steel Company. As Proect wrote, Ural Steel supplied sheet metal to the manufacturer of tanks and other armoured vehicles Ural Vagan Zavod. In 2019, Ural Steel also belonged to Metaloinvest. The company was sold in 2022 to Zagorsk pipe plant. In December 2023, the Mikhailovsky mining and processing was already attacked by a drone. Then the UAV damaged the power supply lines of one of the plant's facilities but the plant itself continued to operate. Metallurgic enterprises have likely become a new target for Ukrainian drones in Russia. On February the 24th, the Novolipetsk Metallurgic Plant, the products of which according to the project are used for the production of weapons, military equipment and machinery was attacked. Since the beginning of the year, Ukraine began regularly striking Russian refineries with which Bloomberg linked the reduction in oil refining at Russian refineries by 380,000 barrels per day by mid-February. Other fuel infrastructure facilities are also being attacked. For example, four days ago, a drone apparently tried to attack the strategic Russia oil depot in St. Petersburg.
