KYIV - The leaders of Britain, France, Germany and Poland headed to Kyiv on Saturday for talks with Ukrainian President Volodymyr Zelenskiy in a show of unity a day after Russia's Vladimir Putin hosted his allies in a Victory Day parade on Red Square.

The summit will discuss a U.S. and European proposal for a 30-day ceasefire in the Russian war in Ukraine that if refused by Moscow would see them jointly impose new sanctions, a French diplomatic source said, adding that the step had not yet been finalised.

Trump has threatened to step up sanctions against Russia but he has also said he could abandon the peace effort if there is no breakthrough. He called on Thursday for a 30-day ceasefire and Zelenskiy said he would be ready to implement it immediately.

Kremlin spokesman Dmitry Peskov was quoted as saying on Friday that Russia supports the implementation of a 30-day ceasefire in the conflict, but only with due consideration of "nuances".

Putin hosted Chinese President Xi Jinping and other leaders at a Red Square military parade on Friday to mark the 80th anniversary of the Soviet Union's victory over Nazi Germany in World War Two, sending a defiant message that he is not isolated.

On the same day, European ministers voiced support for a special tribunal to prosecute the Russian President and his officials for crimes of aggression, showing support for Zelenskiy who ...
