30 years since the genocide in Rwanda: "The international community has let us down" - voila! news. About 800,000 Tutsis were massacred by the Hutu over a hundred days in 1994, when the world stood by and failed to stop the atrocities.

"The lesson we learned is etched in blood," said President Kagame, who then led the rebels who stopped the genocide but was himself accused of mass killing in revenge. The failure of other countries to intervene in the genocide is a source of enduring shame.
