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.

After launching its biggest aerial attack on Kharkiv, Russian forces have now expanded their ground offensive into the Dnipropetrovsk region.

Russia claims Ukraine indefinitely postponed the release while Kyiv maintains it has been delayed until next week.
