Overview
- On Thursday, June 18, a large Ukrainian drone assault struck the Kapotnya (Moscow) oil refinery, sparking major fires, reports of oily 'black rain,' temporary closures at four Moscow airports, and about 16–17 civilian injuries.
- The Russian Defence Ministry said its forces intercepted hundreds of drones nationwide and shot down roughly 180–194 on approach to Moscow while admitting that several drones reached the refinery and other targets.
- President Volodymyr Zelensky described the operation as a justified response to recent Russian strikes on Ukrainian sites and framed the attacks as pressure on facilities that sustain Russia’s war effort.
- Analysts and defence reports say the scale and mix of propeller and jet‑powered drones showed growing Ukrainian long‑range strike capability and helped overwhelm layers of Moscow’s air‑defence network.
- The strike risks tangible effects for Moscow — possible fuel supply and flight disruptions, increased civilian health and environmental harm, and a higher chance of stepped‑up Russian retaliation as Western support for Kyiv expands.
