At least six people have been killed in a wave of Russia strikes on Kyiv, which the Ukrainian President Volodymyr Zelensky has condemned as a “heinous attack”.

The BBC’s James Landale visited the scene of one attack in eastern Kyiv where a drone rammed through a block of flats and left six people dead.

Several other regions were also targeted. A drone attack on a market at Chornomorsk in the south of the country killed two people.
