Kramatorsk, the city where only drones are heard

Source Summary

Only drones can be heard! There is only darkness and the buzzing of the small drones' engines, interrupted from time to time by an explosion when they find a victim. There are others, much larger, that make no noise. Only the detonation is heard. "It's terrifying," Andrei, one of the few remaining inhabitants of Kramatorsk, tells me. Most have been evacuated by government order.
