Russia launched a massive attack on Ukraine overnight into Saturday with hundreds of drones, killing at least one person, part of a stepped-up bombing campaign that has dashed hopes for a breakthrough in efforts to end the more than 3-year-old war.

Russian air defenses destroyed 73 Ukrainian drones overnight, including three heading for Moscow, Russia's defence ministry said on Friday.

In June, Russia's Defense Ministry reported downing a total of 2,368 Ukrainian drones, with an average of almost 79 drones per day across the month. Thus far in July, the Defense Ministry said it has downed 1,516 Ukrainian drones, with a daily average of 89 drones.
