Eyewitness footage has captured flames and thick smoke rising from the Moscow oil refinery following a Ukrainian drone attack. Moscow Mayor Sergei Sobyanin confirmed that a facility at the Gazpromneft-owned refinery was damaged, while Ukrainian President Volodymyr Zelenskiy also acknowledged the strike. Verified through satellite imagery and local landmarks, the video offers a rare glimpse into the growing reach of drone warfare deep inside Russian territory. The refinery, the largest in the Moscow region, plays a crucial role in supplying fuel to the capital and surrounding areas. The incident comes amid a sharp rise in attacks on Russia's energy infrastructure in 2026, raising fresh concerns over supply disruptions and the escalating nature of the conflict.
