Ukrainian drones hit the Moscow Oil Refinery on 18 June 2026, sending thick black smoke over the capital and forcing temporary restrictions at major airports. The strike marked the second attack on the Kapotnya facility in a week and hit a refinery that supplies more than a third of Moscow-region fuel.
Russian officials said air defenses intercepted large numbers of drones, but multiple aircraft movements were disrupted and commercial schedules absorbed immediate knock-on delays. The refinery sits about 15 kilometers from the Kremlin, putting fuel logistics, urban infrastructure, and airport operations under direct pressure. Expect operators to watch for further airspace restrictions and follow-on strikes against energy assets.
