One person was killed and 23 people, including a child, were wounded in a Russian missile strike on an apartment block and houses in the southern Ukrainian city of Mykolaiv in the early hours of Thursday.
Regional governor Vitaliy Kim said the emergency services put out several fires caused by the missile debris and that they were clearing the rubble.
Russia denies deliberately targeting civilians in its full-scale invasion that has killed thousands of people, uprooted millions and destroyed towns.
