Ukraine's President Volodymr Zelensky has accused Russia of "doing everything it can" to prevent a meeting with Vladimir Putin to try to end the war. US President Donald Trump has sought to bring the two leaders together, but he said on Friday "that's like oil and vinegar... they don't get along too well".

Russia’s top diplomat said in an interview released on Friday that “there is no meeting planned” between President Vladimir V. Putin of Russia and President Volodymyr Zelensky of Ukraine. It was the Kremlin’s most direct declaration yet that a summit the White House suggested was imminent was nowhere close to materializing.

President Trump said in a social media post Monday that he had spoken to Russian President Vladimir Putin and set in motion arrangements for a summit at a location to be decided.
