A wave of Russian missiles have hit cities across Ukraine, officials say.
Kyiv Mayor Vitaly Klitschko said there had been several blasts in the capital, causing at least one death. A hotel has also been damaged.
The attacks happened two days after Russia carried out one of the largest air strikes since the start of the war.
Ukraine President Volodymyr Zelensky had warned Russia could launch more attacks to make Ukrainians “celebrate the New Year in darkness”.
