Ukraine and Russia traded accusations Sunday of violating a one-day Easter truce, which was only announced by Moscow a day prior and that has since expired.

Ukrainian and Russian officials accused each other of violating a ceasefire and truce that was supposed to temporarily halt the military conflict during the Easter holiday on Sunday. And, while they were accusing each other of violating the Easter “truce” they also agreed to a prisoner exchange of over 500 captured service members.
