Russian forces have launched a large-scale drone assault across Ukraine, where officials said three people were killed and 64 others wounded.

A concentrated, nine-minute-long Russian drone attack on Ukraine's second largest city of Kharkiv in the middle of the night killed three people and injured 64, including nine children, Ukrainian officials said on Wednesday.

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.
