The announcement was made by leaders of Britain, France, Germany, Poland and Ukraine after a meeting in Kyiv, and a phone call with President Trump.

It’s a proposal that the Kremlin can neither reject nor accept, but one that may force it into an awkward choice, revealing Russian President Vladimir Putin’s true appetite for his brutal war of choice.

European leaders have urged Russia to agree to an unconditional 30-day ceasefire with Ukraine starting on Monday. The call was issued at a meeting of the "coalition of the willing" in Kyiv. The leaders of France, Germany, the UK and Poland were hosted by Ukraine's Volodymyr Zelensky, while others joined remotely.
