Two rhinos die in Chad after being relocated from South Africa.

Two of six critically endangered black rhinos have died of unknown causes five months after being flown from South Africa to Chad in a pioneering project to re-introduce the animals Rhinos in Chad were wiped out by poaching nearly 50 years ago, and the six rhinos were intended to establish a new population in the country after intensive anti-poaching measures were put in place to protect them. 
                                        There are fewer than 25,000 rhinos left in the wild in Africa due to a surge in poaching, and only 5,000 of them are black rhinos. Black rhinos are rated as critically endangered by the International Union for Conservation of Nature. Rhinos are targeted to feed a booming demand for rhino horn in China, Vietnam and other Asian countries, where it is believed to have medicinal qualities.
