Mass evacuation from powerless Kyiv amid severe cold

“After this attack, 5,635 buildings lack heating,” Klitschko writes on Telegram.

He is referring, among other things, to the large apartment buildings that Kyiv has had thousands of since Soviet times. They are home to hundreds of thousands of people.

Klitschko says that around 600,000 residents of the capital have temporarily left the city, following a call from the mayor on January 9.

According to President Volodymyr Zelenskyy, Russia's attack consisted of "a significant number of ballistic and cruise missiles" and "over 300 attack drones."
