MOSCOW/WASHINGTON (REUTERS)
US President Donald Trump was due to speak to Russia's Vladimir Putin on Monday about peace in Ukraine after Washington said there was an impasse over ending Europe's deadliest conflict since World War Two.
Trump, who says he wants to be remembered as a peacemaker, has repeatedly called for an end to the war.
Under pressure from Trump, delegates from the warring countries met last week in Istanbul for the first time since 2022, after Putin proposed direct talks and Europeans and Ukraine demanded an immediate ceasefire.
Less than an hour before the 10 a.m. Eastern Time (1400 GMT) call, US Vice President JD Vance told reporters that Washington recognised there was an impasse in ending the war - and that if Moscow was not willing to engage, then eventually the United States would have to say it was not its war.
