Serengeti officials in poaching inquiry

Four senior wildlife officials and dozens of game wardens have been suspended after poachers killed two critically endangered rhinos in the Serengeti park.

The acting director of the national parks authority and the Serengeti's chief warden were among those under investigation.

A female rhino, one of five black rhinos moved to the Serengeti from South Africa in 2010, and a calf were killed for their horns. The animals had been fitted with electronic chips and were being protected by an elite ranger unit.
