In a late-night incident, flames engulfed a Rosneft-owned oil refinery in Tuapse, Russia, close to the Ukrainian border. The fire, centered around a vacuum unit, prompted a swift response from firefighting teams. Mayor Sergey Boyko confirmed the blaze was contained after approximately 2 hours, with no reported casualties. The incident disrupted flights at the Sochi international airport, diverting planes to Mineralnye Vody Airport for safety. While the cause is under investigation, Ukrainian sources raise the possibility of a drone attack sparking the refinery fire.
