At least 11 people were killed and 30 wounded, including five children, in Russian missile and drone attacks on Ukraine's eastern city of Dobropillia overnight , Ukrainian Interior Ministry said on Saturday.

Another three civilians were killed in a drone attack on the Kharkiv region in the northeast, the ministry added.
