At least four people have been killed in a large-scale retaliatory strike by Ukraine on Russia's regions, including Moscow, the Russian authorities have said.

The wave of almost 600 Ukrainian drones struck overnight across 14 Russian regions, as well as the Crimean peninsula and the Black and Azov seas, the Russian defence ministry said on Sunday, with the region around the capital among the worst-hit.
