Russian troops are gathering troops 90 kilometres from Kharkiv for another push into Ukraine, president Volodymyr Zelensky warned on Sunday.

In a video address to world leaders, Mr Zelensky said: “Russia is preparing for offensive actions also 90 kilometres north-west from here – they gather another group of troops near our border.”

Addressing suggestions this week that Russian president Vladimir Putin could be open to peace talks, Mr Zelensky added: “The one who does all this doesn’t want peace.”

Kyiv is struggling to hold the eastern front as the Kremlin’s forces advance. Russia has gained more territory in 2024 than it lost control of during Ukraine’s much-hyped counteroffensive in the summer of 2023, according to analysts.

The Ukrainian president also used his English-language speech to urge US president Joe Biden and China’s president Xi Jinping to attend a peace summit in Switzerland next month. “I am appealing to the leaders of the world... to president Biden, the leader of the United States, and to president Xi, the leader of China... Please support the peace summit with your personal leadership and participation,” he said.
