From Kigali to Khartoum: Africa's drone revolution

Drones, or unmanned aerial vehicles (UAV), have been used for more than three decades, but in the last few years drones are increasingly being developed and used for commercial purposes. But while inventors and entrepreneurs in Western countries struggle with strict regulations, many African countries are proving very innovative and accepting in terms of drone usage across industries. From Kigali to Khartoum, pioneers are using drones to tackle some of the continent's current challenges. In Rwanda, drones deliver blood to almost half of the country's blood transfusion centres. In Malawi, UAVs deliver HIV test kits to and from remote parts of the country.
