'They Sound Like Motorbikes': Ukrainians Say They Can Hear Iranian Suicide Drones Coming

Russia has resorted to using Shahed-136 drones from Iran in its war on Ukraine. Ukraine says it's already downed many of the drones, which work by slamming into their intended target, laden with explosives. Ordinary Ukrainians say they can already recognize the sound of the drones, which use two-stroke engines like lawnmowers or motorbikes. Iran has denied supplying the drones to Russia.
