According to the sources, the attack resulted in a fire at the oil storage facility, damaging several structures, including a rail overpass and a hydrocracking unit used to remove impurities from petroleum products.

In December, Ukrainian drones targeted oil depots and refineries in Smolensk, Oryol, Bryansk and Rostov — an area that had previously been targeted in July. The General Staff of Ukraine’s Armed Forces claimed that the July attack on the Rostov refinery destroyed 1.5 million tons of oil and oil products worth $540 million (£433m).
