Ukrainian President Volodymyr Zelenskiy said on Sunday that a ceasefire with Russia in its more than three-year-old war was possible at any moment and called on Kyiv's allies to apply greater pressure on Moscow to put the measure in place.

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

Russian President Vladimir Putin declared a three-day ceasefire in the war with Ukraine next month to celebrate the Soviet Union’s victory over Nazi Germany during World War II.
