Illegal poaching in Africa is being fuelled by a growing demand for ivory from wealthy consumers in China, and across Asia.
The poachers who slaughtered 12 elephants at the weekend were likely big-time gangsters fuelled by consumer demand in the Far East.
A family of 12 elephants has been killed and their tusks hacked off in the worst recorded incident of ivory poaching in Kenya's history.
