Tuapse refinery fire enters fourth day

The major fire at the Tuapse oil refinery and marine terminal in Russia has entered its fourth day following a Ukrainian drone attack on April 20. Firefighting efforts remain ongoing, with the sustained blaze continuing to produce heavy smoke and environmental fallout. An oil slick off the coast is reportedly expanding by the hour, raising concerns about marine pollution and ecological damage. The attack is part of Ukraine's sustained campaign targeting Russian energy infrastructure to disrupt fuel supplies and military logistics.
