Ukraine's air force says it detected 184 missiles and drones, causing damage to energy infrastructure across the country.

Russia attacked Ukraine's energy system and some cities with cruise and ballistic missiles plus drones, Ukraine's President Volodymyr Zelenskiy said.

A large-scale Russian missile and drone attack targeting Ukraine ’s energy system on Christmas Day has been condemned as “inhumane” by president Volodymyr Zelensky. Half a million people were left without heating in Kharkiv in temperatures just a few degrees above freezing, as blackouts were reported in Kyiv and other regions.
