The diggers' hoes scrape the brown soil, looking for - and often finding - human bone fragments. The women then wipe the bone pieces with their hands as others watch in solemn silence.
The digging goes on, a scene that's become all too familiar in a verdant area of rural southern Rwanda, where the discovery in October of human remains at the site of a house under construction triggered another search for new mass graves believed to hold victims of the 1994 genocide against Rwanda's Tutsi.
