Russia and Ukraine accused each other of thousands of attacks that violated the one-day Easter ceasefire declared by President Vladimir Putin, with the Kremlin saying there was no order to extend the pause in frontline fighting, Reuters reported.

Washington said it would welcome an extension of the truce, and President Volodymyr Zelenskiy reiterated several times Ukraine's willingness to pause strikes for 30 days in the war.

But Putin, who sent thousands of Russian troops into Ukraine in February 2022 and who ordered on Saturday the halt in all military activity along the front line until midnight Moscow time (2100 GMT) on Sunday, did not give orders to extend it, according to Reuters.
