Massive Russian strikes on Ukraine’s second-largest city killed at least five people on Saturday, officials said, one night after Moscow carried out one of the war’s largest aerial assaults on Ukraine.

Russia attacked the eastern Ukrainian city of Kharkiv at night and in the evening with drones, missiles and guided bombs, killing at least four people and injuring more than 60, including a baby, local officials said on Saturday.

Ukraine says that a large Russian drone-and-missile attack has targeted the city of Kharkiv, killing at least three people and injuring 21.
