Zelenskiy said he discussed air defences with Trump and agreed to work on increasing Kyiv's capability to "defend the sky".

President Trump said on Thursday that a phone call with President Vladimir V. Putin of Russia had not resulted in any movement toward ending the war in Ukraine, adding that he was “not happy” with the conflict grinding on. “I didn’t make any progress with him at all,” Mr. Trump told reporters.

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.
