At least four people killed in Russia as Ukraine launches retaliatory strikes

Wave of almost 600 drones launched across 14 regions, after Moscow's deadly three-day attack on Ukraine last week

One of Ukraine's largest ever drone strikes against Russia's regions, including Moscow, has killed at least four people and wounded a dozen more, 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 area around the capital among the worst-hit.
