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

Russia bombarded six regions of Ukraine in one of its largest aerial attacks of the three-year war, Ukrainian officials said on Friday.

At least three were killed and 49 injured in missile and drone strikes that focused on Kyiv, days after a daring covert attack on Moscow’s bomber fleet.
