Three persons, including a woman in her 70s, were killed and three others were injured after a Russian missile attack struck the northeastern Ukrainian village of Chuhuiv in the Kharkiv region overnight, the regional governor said on Saturday.

Rescuers were searching through the rubble after the strike damaged a two-story residential structure, a school, and a shop, according to Governor Oleh Synehubov and the police.

A regional police official said Russia fired four missiles at the town from near its western city of Belgorod at around 0330 local time.

Russia, which invaded Ukraine on Feb. 24, denies targeting civilians in what it describes as a special military operation.

Ukraine’s defence ministry spokesperson said on Friday that only 30% of Russian strikes were hitting military targets, with the rest landing on civilian sites. That assertion could not be verified by Reuters.
