Officials say a Russian drone barrage has targeted the center of Kharkiv, injuring nine people and damaging a maternity hospital in Ukraine’s second-largest city.

Ukrainian drone and shelling attacks killed three people in Russia on Friday, while Russian bombardments on east Ukraine forced the evacuation of a maternity centre in Kharkiv and wounded nine.

Authorities said the boy died following a strike on a village in Kherson amid Russia's increased bombardment of Ukrainian cities.
