The head of Ukraine's southern Kherson region says that Russian attacks during the 30-hour Easter ceasefire unilaterally declared by President Vladimir Putin over the weekend killed three people in the region.

Russian forces ended a short-lived cease-fire by launching a wave of aerial attacks against cities across south-eastern and central Ukraine overnight, including the capital, Kyiv, Ukrainian authorities said.

Russia and Ukraine on Monday each accused the other of violating Russian President Vladimir Putin’s proposed Easter ceasefire thousands of times, drilling home the immense challenges facing the White House as it plows ahead in its quest to quickly end the war.
