In the town of Tuapse on Russia's Black Sea coast, attacks by Ukraine on the oil refinery caused large fires and an environmental disaster. The fires at the Rosneft-owned refinery resulted in black rain, the air filled with toxic gases, and many birds died covered in fuel. Authorities stated that the fire was brought under control but its effects continue, declaring a state of emergency and closing schools. Local residents reported seeing black rain droplets on their clothes and skin when outside. Environmentalists emphasized that this event is the largest environmental disaster in the region in recent years. Additionally, an area of 10 square kilometers in the Black Sea was polluted due to the oil spill, harming birds and other aquatic life. Local volunteers are working on cleaning and rehabilitating the affected animals. Authorities have mobilized all resources to extinguish the fire and reduce environmental impacts. It is noted that air pollution in the region may spread to neighboring areas. The attacks are considered part of Ukraine's operations targeting Russia's energy infrastructure to hit fuel export revenues.
