Russia has launched a "massive" drone attack on the capital, Kyiv Mayor Vitali Klitschko has said, while a maternity ward in Odesa has also been targeted. The Odesa drone attack hit medical facilities and residential buildings, killing a 59-year-old man and injuring four, Governer Oleg Kiper said on Telegram.

Russia flattened a section of an apartment block in Kyiv on Tuesday in its deadliest attack on the Ukrainian capital this year — part of a barrage of hundreds of drones and dozens of missiles that killed at least 18 people and wounded 151 others.

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.
