Russian airstrikes on Kyiv have killed at least 18 people and wounded dozens in the most deadly night raid on the Ukrainian capital since the Alaska summit between Vladimir Putin and Donald Trump.

Seventeen people were reported killed when a five-storey residential building in the eastern Darnytskyi district was struck in the middle of the night, said Svitlana Vodolaha, a spokesperson for the state rescue service.

A further 10 were still unaccounted for but not all may have been the building at the time, she added. There were 200 rescuers and 59 rescue vehicles on site and the search and clean-up effort was expected to go on into the night.

The victims included four children, Vodolaha said. Ukraine’s interior minister, Ihor Klymenko, had earlier said a child as young as two had died at the scene.
