A residential building was struck by a Russian missile on Monday morning in Ukraine’s Kharkiv, officials said.

The missile struck a six-storey residential building in the besieged country’s northeastern part, officials from Kharkiv’s state emergency service said. Casualties from the strike are not immediately clear.

Besides, Ukrainian rescue workers have recovered 15 bodies after Russian Uragan rockets hit a five-story apartment block, collapsing the building in the eastern Donetsk region, officials said.

More than 20 people may still be trapped in the wreckage, the local branch of the emergency service in the town of Chasiv Yar said on Facebook.

Emergency workers late on July 10 pulled a man who had been trapped for almost 24 hours out of the rubble, bringing to six the number found alive. The man was rushed to a hospital after being pulled out by rescuers, who earlier said they were in contact with at least three people trapped under the ruins.
