Russia launched its largest drone attack on Ukraine of the conflict to date on July 3, days after the Pentagon paused weapons deliveries to Ukraine.

At least three children were among 27 people wounded as a result of a Russian drone attack on Ukraine's second-largest city of Kharkiv overnight that damaged apartments and a kindergarten, Ukrainian authorities said on Monday.

Russia launched 550 drones and missiles across Ukraine overnight in the largest aerial assault since the war began. The capital Kyiv was the primary target.
