Russia launched a record number of drones at Ukraine overnight into Friday, striking multiple buildings and residential areas, hours after US President Donald Trump said he had made “no progress” towards a ceasefire deal in a phone call with his Russian counterpart Vladimir Putin.

Putin told Trump during the call that Russia won’t back down from its goals in Ukraine, according to Yuri Ushakov, a close adviser to the Russian president, despite the U.S. leader’s calls for a speedy end of the conflict.

President Donald Trump revealed his growing frustration with Russian President Vladimir Putin on Thursday, telling reporters he made no progress “at all” on ending the Ukraine war despite a lengthy phone call.
