Overview
- Ukraine launched coordinated drone and cruise-missile strikes overnight on June 10–11, 2026, that both sides say affected Cheboksary, Samara, Vladimir and Sevastopol.
- Russian authorities and local governors report damage at the VNIIR-Progress military plant in Cheboksary and say assessments of casualties and infrastructure damage are under way.
- President Volodymyr Zelensky publicly credited Flamingo/F-5 long-range strikes on military and oil-sector sites as the operation used to target components and supply chains.
- The Russian Ministry of Defense said it neutralized up to 326 Ukrainian drones across many regions and Moscow's mayor said four drones were shot down over the capital.
- A drone impact and fire at the Sevastopol defence museum provoked strong official condemnation and reports of a possible hit on a Rosneft refinery in Samara remain unconfirmed as investigations continue, raising the risk of broader escalation.
