Russia has launched fresh airstrikes on Ukraine, with heavy fighting reported in the Donetsk region. Russian authorities claim their air defence systems intercepted and destroyed more than 50 Ukrainian drones, while Ukraine says its forces successfully targeted Russian oil refineries, ammunition depots, and radar systems. A state of emergency has been declared in the Russian city of Ryazan after a Ukrainian drone attack reportedly killed four people and injured 28 others. President Volodymyr Zelensky has demanded a “just and tangible” international response.
