New waves of deadly Russian missiles pounded Ukraine overnight Sunday while long range drone attacks by Kyiv sparked travel chaos at Moscow’s airports.

Residents of Kyiv and other major Ukrainian cities faced another sleepless night on Sunday as Russia launched 450 missiles and drones overnight into Monday, Ukraine’s Air Force said.

The majority were shot down but 23 struck across three locations and debris from intercepted missiles landed in 12 areas, it added.

Nationwide air raid warnings were issued in most regions of Ukraine, with local authorities reporting at least two people killed and 16 wounded in the past 24 hours.

“Russian strikes are always an assault on humanity – in Kyiv, a kindergarten caught fire, along with residential buildings and other civilian infrastructure,” Ukrainian President Volodymyr Zelensky said.
