A pre-dawn Russian missile salvo on the Ukrainian capital of Kyiv threatens the prospect of peace talks, Volodymyr Zelensky has said.

The strikes on Wednesday killed one and injured four, including a nine-year-old girl, and sparked several fires in the city of three million, Ukrainian officials said.

Prospects for renewed peace negotiations to end the war that Russia launched on Ukraine nearly three years ago have increased after Donald Trump, the US president, said he had been in contact with Kyiv and Vladimir Putin.

Mr Zelensky said on Tuesday that Kyiv would soon hold talks with US officials.

But the Wednesday morning strike prompted Kyiv to warn that such attacks put the prospect of peace in jeopardy.
