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.

Amidst ongoing hostilities, Ukrainian President Volodymyr Zelenskyy criticised Russia's 72-hour ceasefire as superficial.
