Russia reported that 355 Ukrainian drones were intercepted over its territory, with a drone strike in Ryazan killing three people and injuring 12, while causing industrial damage. Concurrently, Ukraine faced massive Russian aerial barrages targeting Kiev and other regions, resulting in 24 confirmed deaths, including three children, and 47 injuries. Kiev mayor Vitali Klitschko declared a day of mourning for the victims. Ukraine reported that Russia launched hundreds of drones and missiles, while Ukrainian air defense forces claimed to have intercepted 652 drones and 41 missiles during specific waves of the attack.
