The mayor of Kyiv has issued a stark message to residents of the Ukrainian capital after another wave of horror attacks. The warning comes after several Russian strikes on key infrastructure targets have left many people in Ukraine facing freezing temperatures without heating or power.

Vitaly Klitschko said that 1,940 high-rise apartment blocks in the capital are still without heating following Russian strikes on 9 and 20 January. Posting on the social media, he advised people to stock up on necessities. He said: “Let me put this bluntly: this is an extremely difficult situation, and it can get worse.If anyone can leave the city and move somewhere where there is power and heating, do not reject this option.”

He adds that “resilient points” are being set up across the city, where temperatures have been hovering at -10C (14F).
