Drones to deter poachers

Targetted by poachers: The horns of these white rhinos are highly sought-after by Asians. Poachers have killed 515 rhinos so far this year in South Africa. Last year, 668 rhinos were killed, a record high that could be surpassed if the poaching continues at today's pace. - AFP

Unmanned aerial vehicles are being deployed to stem the killing of rhinos in Africa.

The exact location of the anti-poaching operation is secret, as is the number of rangers who will be on duty. Also confidential: where the drones will fly as they search out poachers intent on slaying rhinos for their horns – one killed every 11 hours in South Africa alone.
