President Donald Trump said Friday that he was unsure if he’d be able to end Russia’s war against Ukraine, a far cry from his promise to swiftly put a stop to the conflict that he made on the campaign trail.

Ukrainian President Volodymyr Zelenskiy said on Saturday that his latest conversation with U.S. President Donald Trump this week was the best and "most productive" he has had to date.

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.
