Russia has launched one of the largest aerial assaults of the war, firing 656 drones and 73 missiles at Ukraine in a massive overnight attack that primarily targeted Kyiv, according to Ukrainian officials. Ukrainian authorities said at least 18 people were killed and more than 100 injured as explosions rocked the capital and several other regions. Ukraine's air force reported that air defenses intercepted or neutralized hundreds of incoming threats but confirmed that multiple missiles and drones reached their targets. Officials also said the barrage included eight Zircon hypersonic missiles, marking one of the largest reported uses of the advanced weapon during the conflict. The attack comes just days after Ukrainian President Volodymyr Zelensky claimed that Ukrainian forces had struck 15 Russian oil refineries between January and May, disrupting Russia's energy infrastructure.
