Russian officials say air defence systems intercepted more than 40 UAVs over the Voronezh Region during a major overnight assault. At the same time, Ukrainian long-range strikes reportedly targeted the Kuybyshevskiy oil refinery in Samara and a military-linked manufacturing facility in Cheboksary. The attacks highlight Kyiv’s growing ability to strike deep inside Russian territory while intensifying pressure on critical infrastructure. The developments come as President Volodymyr Zelensky says Ukraine is ready to share its drone interception experience with Nordic and Baltic partners.
