From the BBC News:

The Congolese Nature Conservation Institute (ICCN) is reported to have brought the charges against Honore Mashagiro - one of its members.

Ten gorillas were killed in 2007 in the Virunga National Park, a Unesco world heritage site.

The park is in a volatile region where rebels have set up a base.

The area is also home to more than half of the world’s last 700 mountain gorillas living in the wild.

Six other foresters could be questioned over the killings, and their role in trapping and slaughtering the animals on the alleged orders of Mr Mashagiro, reports say.
