The United States and Ukraine said they had created an "updated and refined peace framework" to end the war with Russia that apparently modified an earlier plan drafted by the Trump administration which Kyiv and its allies saw as too sympathetic to Moscow.

As for Mr Trump, he again betrayed his underlying bias: sympathy for Russia and indifference to Ukraine. Ahead of the Geneva talks he dismissively said Mr Zelensky “can continue to fight his little heart out” if no agreement were reached, and complained on social media that “UKRAINE ‘LEADERSHIP’ HAS EXPRESSED ZERO GRATITUDE FOR OUR EFFORTS.”

U.S., Ukrainian and European officials gathered in Switzerland on Sunday for talks on the contentious American-Russian peace plan put to Kyiv this week.

Ukrainian President Zelensky warned his country faced "one of the most difficult moments in our history", as Trump has applied pressure on him to accept the deal. In a joint statement issued at the G20 summit in South Africa on Saturday, Ukraine's allies publicly pushed back against the plan.
