Russian forces have launched a large-scale drone assault across Ukraine, where officials said three people were killed and 64 others wounded.

Explosions were heard in Kyiv amid an attack by Russian Shahed kamikaze drones, according to the city’s mayor, Vitalii Klitschko, the Kyiv City Military Administration, and RBC-Ukraine's own correspondent.

Russia launched 315 drones at Ukraine overnight into Tuesday, in what Ukrainian President Volodymyr Zelensky said was “one of the largest” attacks on the capital Kyiv, with local officials in the southern port city of Odesa also reporting a maternity ward there had been hit.
