Since April 1994 Rwanda has become a synonym for one of the worst genocides of the 20th century. An estimated half a million people, mostly Tutsi, were killed in the course of a carnage that claimed twice as many victims in one month as the Bosnian civil war in two years. To this must be added almost as many deaths caused by military engagements, cholera, dysentery, famine, and sheer human exhaustion.
