Russia launched a massive overnight drone and missile attack on Ukraine, using 537 munitions, according to Ukraine's air force. Ukraine's air defenses, aided by US-supplied F-16s, shot down a significant number. However, one Ukrainian F-16 pilot, Lt. Col. Maksym Ustimenko, was killed while defending against the onslaught. The attack prompted a response from Poland's air force, which scrambled jets before standing down. Ukrainian President Zelenskyy vowed to investigate Ustimenko's death and called for increased air defenses.
