The head of the Tatarstan region, Rustam Minnikhanov, said a Ukrainian drone hit a hostel, killing nine people. Local video footage showed Ukrainian drones buzzing above the city’s skyline, flying low over grey and box-like Soviet-era apartment blocks.

Russia’s defence ministry said it had intercepted 456 Ukrainian drones flying above Russian territory and annexed Crimea.
