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.

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.

The president repeatedly said on the campaign trail that he would bring an end to the war in the first 24 hours of his second term.
