China is to ban the sale of drones in Beijing and permits will be required 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.

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.

The BBC’s Laura Bicker looks into why China has tightened regulations on drones, with authorities citing public safety concerns.
