The rest of her 11 family members were all killed on those occasions during mass killings in the 1994 genocide.

- PHOTO TAKEN 23DEC01 - The bones of victims of the Rwandan genocide wait to be sorted and placed in display cases at a planned museum set to open in the capital Kigali in February 2002. The museum will feature the remains of thousands of dead, their names and personal details. There will also be a library, video presentations and a cafeteria.
Up to 800,000 Tutsis were killed in 1994 by Hutu extremists in one of modern history's worst bouts of ethnic slaughter.
