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.

With diplomatic efforts between Ukraine and Russia at a halt, a new "massive" drone attack rocked Kyiv on Monday, killing at least five people and injuring about 20 more, after Ukraine said it would increase the "scale and depth" of its operations against Russian energy and military infrastructure.
