Kyiv's Mayor Vitaly Klitschko added to the pressure on Ukrainian President Volodymyr Zelensky to compromise on recognizing Russian control of the land Moscow currently occupies. Klitschko has clashed with Zelensky previously and is widely seen as a potential rival when Ukraine next holds presidential elections.

The Ukrainian leader was speaking from South Africa where he has cut short a trip due to overnight missile and drone attacks on his country.
