Hours later, Russia launched a glide bomb and a drone at the front-line town of Kostyantynivka in eastern Ukraine, killing four civilians and injuring a fifth, the prosecutor’s office said. The drone struck a car in which a married couple were travelling, killing the 39-year-old woman and 40-year-old man on the spot, it said.

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.
