Nearly half a million households were left without power on Christmas Day in frigid weather after further missile attacks by Russia on Ukraine's damaged power grid, according to multiple reports.

Russia launched aerial attacks on Ukraine’s energy sector “on a massive scale” overnight into Wednesday, local authorities said, with explosions reported across the country amid intensified bombardments that have left Ukraine in a precarious position while the war grinds into a third winter.

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