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.

The warring sides also exchanged prisoners in one of the few results of talks last week, and Russia reported new attacks on the front line.

In yet another massive overnight attack, Russia launched a total of 499 drones and missiles at Ukraine on Monday. According to the official statement by Ukraine’s Air Defence forces, 479 of them have been downed.
