Russia bombarded Ukraine’s second-largest city with massive strikes in the early hours of Saturday, its mayor said, killing at least three people, one night after Moscow carried out one of the war’s largest aerial assaults on Ukraine.

Photos showed burnt and partially destroyed houses and vehicles, and rescuers carrying the injured to safety and removing debris.

One of the bombs hit the Children's Railway, a popular gathering place for families in central Kharkiv, Governor Oleh Syniehubov said.
