Poachers killed around 10 percent of Kenya's rhino population last year, according to the World Wildlife Fund (WWF).

Horns can fetch up to $90,000 a kilo and are in demand across Asia for their perceived medicinal qualities.

The WWF and Kenyan rangers have responded to illegal poaching by launching a programme that involves sawing off rhinos' horns and inserting high-tech tracking devices under their skin.
