At least three children were among 27 people wounded as a result of a Russian drone attack on Ukraine's second-largest city of Kharkiv overnight that damaged apartments and a kindergarten, Ukrainian authorities said on Monday.

Russian drones attacked the Ukrainian city of Kharkiv early on Monday, according to Governor Oleh Syniehubov. Mayor Ihor Terekhov said at least 27 people were injured in the strikes.

Russia launched a record number of drones at Ukraine overnight into Friday, striking multiple buildings and residential areas, hours after US President Donald Trump said he had made “no progress” towards a ceasefire deal in a phone call with his Russian counterpart Vladimir Putin.
