One of the hardest-hit areas was the city of Kharkiv in northeastern Ukraine, where 17 attack drones struck two residential districts, Mayor Ihor Terekhov said.

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.
