Drones are changing the nature of warfare. But those at the forefront are ordinary citizens who volunteered to fight for their country

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.

It was the latest in a series of almost weekly large-scale missile and drone attacks. President Trump said he “didn’t make any progress” with President Vladimir V. Putin of Russia.
