At night, Russia shelled Mykolaiv with four Kalibr missiles launched from the Black Sea, President Volodymyr Zelenskyy has said on Telegram.
High-precision weapons were aimed at private houses, a historic building and a high-rise building, he added.
"The country-invader never ceases to prove that the main goal of this war is terror and the destruction of Ukrainians and everything Ukrainian," he said. "At the moment, it is known about 1 killed and 23 wounded, including a child."
He pledged Ukraine would identify the culprits and hold them accountable.
