Overview
- The largest waves of drone attacks struck Russian territory on June 20–21, with explosions reported at the Kapotnya/Gazprom Neft refinery outside Moscow and multiple intercepts over the capital.
- Russian‑occupied Kerch on Crimea’s eastern tip was hit by a separate mass attack that local authorities say killed at least four people, injured dozens, caused fires at port and fuel facilities, and forced suspension of bridge and ferry traffic.
- Moscow and the Russian Ministry of Defence publicly reported hundreds of drones shot down across multiple regions, with mayoral and defence figures offering varying tallies as officials highlighted strong air‑defence activity.
- Independent verification is limited and analysts note open questions about causation after videos circulated suggesting some blasts could have been caused by Russian air‑defence fire rather than direct hits by drones.
- The campaign reflects Kyiv’s push to use domestically produced long‑range drones to isolate Crimea by targeting fuel and logistics, a tactic that is straining local services, cutting civilian fuel sales, and prompting diplomatic concern in Europe.
