PRAGUE, May 4 - President Volodymyr Zelenskyy 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, Reuters reported.

Zelenskyy, speaking at a joint news conference in Prague alongside Czech President Petr Pavel, said that unless increased pressure were applied, Kremlin leader Vladimir Putin would take no real steps to end the conflict.

"We believe that without increased pressure, Russia will not take real practical steps to end the war. Today marks the 54th day that Russia has ignored even the American proposal to completely cease fire," Zelenskyy told reporters.

"We believe that a ceasefire is possible at any moment, even starting today, and should last at least 30 days to give diplomacy a real chance."
