The Ukrainian president says he was informed the U.S. would divert key defensive weapons from Ukraine to the Middle East.

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.

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.
