Russian President Vladimir Putin on Monday declared a unilateral three-day ceasefire in Ukraine next month, a move met with skepticism by Ukrainian officials who demanded the Kremlin leader immediately accept a longer truce proposal from the United States that he has so far rejected.

President Trump "wants to see a permanent ceasefire first, to stop the killing, stop the bloodshed," press secretary Karoline Leavitt said.

(Reuters) - Ukrainian President Volodymyr Zelenskiy said on Monday that the world did not want to wait until May 8 for Kremlin leader Vladimir Putin's announced ceasefire in the more than three-year-old war only to be in effect for a few days.
