China will ban the sale of drones in Beijing and require permits to fly them under new rules that take effect on Friday.

Drones and key components will be prohibited from being sold, rented or brought into the Chinese capital. Drone owners will also be required to register their devices with the police.

China has gradually tightened regulations on drones in recent years, with authorities citing public safety concerns.

Drones and flying taxis are part of the so-called low-altitude economy, a strategic priority for China that is expected to generate more than two trillion yuan ($290bn; £217bn) by 2035.

In some Chinese cities, drones are a common sight, used for food delivery, agriculture and cleaning buildings.
