Rangers back on the job in the Congo despite war

In the Congo gorillas are living in a war zone, literally.

"If we are not here then no one can stop them being killed.”
- Dusabimana John, ranger from Virunga National Park, Africa's oldest national park. Virunga is one of the last homes of the endangered mountain gorillas. Almost a third of the 700 remaining in the world live in the forest. Others live in national parks in Rwanda and Uganda.
