Gorilla conservationist Dian Fossey remembered

Rwandans are commemorating the 20th death anniversary of Dian Fossey. The ceremonies were held in the Volcanoes National Park, where she had had her research base. It has never been established who killed her in her jungle cabin in 1985.She spent two decades working among Rwanda's rare mountain gorillas. Only about 700 gorillas survive in the remote range of volcanoes spanning the borders of Rwanda, Uganda and the Democratic Republic of Congo. A third of them live in Rwanda.
