7 people, including a 6-year-old girl, were killed when a Russian missile struck a theatre in the northern Ukrainian city of Chernihiv.
Police say 15 children were among the 144 people wounded.
Officials says at least 25 people were in hospital.
Among the victims were people who had been celebrating an Orthodox Christian holiday at church.
A main square and a university building were also damaged in the attack.
The UN has called it "heinous", while Ukrainian President Volodymyr Zelensky has vowed a firm response by Ukrainian soldiers to a "terrorist attack".
