Mass drone attacks in Ukraine foreshadow the 'future of warfare'

A little before 7am on Monday, people in Kyiv heard a whining sound overhead before identifying where it was coming from – a group of "kamikaze" drones flying into the city. Drones have been widely used on both sides of the Ukraine conflict, but these were the first Russian attacks that deployed swarms of the aircraft. Videos and images began to circulate on social media of the drones flying directly over urban infrastructure such as power stations, residential buildings and railways as civilians and soldiers tried to shoot them down with guns. About 28 were launched on Monday morning in Kyiv. At least four civilians were killed after one of the aircraft hit a residential building.
