** ED'S NOTE: GRAPHIC CONTENT**FILE - In this Sunday, July 31, 1994 file picture, a bulldozer operated by a French soldier shovels bodies into a mass grave at the Kibumba refugee camp in Rwanda near Goma, Zaire. More than 1 million Rwandans had fled refugee camps in eastern Zaire where cholera spread. Peace studies experts who tally the dead from wars are divided over whether such victims are properly counted as "war victims" when they die of disease and deprivation caused by war, rather than actual battle wounds.
