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.

Zelenskiy, speaking at a joint news conference in Prague alongside Czech President Petr Pavel, also said that Ukraine hopes to receive 1.8 million shells in 2025 under a Czech initiative to provide military assistance.

Russia plans a three-day ceasefire in Ukraine from May 8-10 for WWII commemorations. Putin emphasizes immediate retaliation if Ukraine attacks. Zelenskiy demands a longer ceasefire, at least 30 days.
