Russian strikes hit more than a dozen locations across Ukraine’s capital Kyiv overnight into Friday, including residential areas, a local official said, hours after US President Donald Trump said he had made “no progress” towards a ceasefire deal during a phone call with his Russian counterpart Vladimir Putin.

Russia unleashed a record air strike on Ukraine, as US President Donald Trump expressed disappointment over the outcome of his latest phone call with Vladimir Putin aimed at bringing an end to the war.
