Russia launched a drone attack on Kyiv overnight into Tuesday, with air raid sirens blaring for hours and residents hearing regular explosions, and local officials reporting damage to residential buildings and at least two people wounded.

Russia launched one of its largest air strikes on Kyiv in over three years of war and struck a maternity ward in the southern city of Odesa in attacks that killed at least two people, officials said on Tuesday.

The attack used almost 500 drones and missiles, breaking a record set just days earlier, as Russia tries to overwhelm Ukraine’s air defenses, which shot down most of the weapons.
