Seven people — including a 6-year-old girl — were killed, 144 wounded and 41 were hospitalized after a Russian missile struck a central square in the historic northern Ukrainian city of Chernihiv on Saturday, Ukrainian officials said.

"I am sure our soldiers will give a response to Russia for this terrorist attack," President Volodymyr Zelenskyy said in his nightly video address, delivered early on Sunday at the end of a visit to Sweden. "A notable response."

He said that of the 144 people injured, 15 were children, and named the girl killed as Sofia. Fifteen others were police officers, Interior Minister Ihor Klymenko said on Telegram. Klymenko said most of the victims were in vehicles, crossing the road, or returning from church.
