Rwanda and the Strife in the Democratic Republic of Congo

After the 1994 genocide in Rwanda, world leaders said they'd never let it happen again. But another humanitarian disaster is taking shape in Rwanda's neighbor. The Democratic Republic of Congo, a country the size of Western Europe, is rich in minerals but desperately poor in infrastructure. More than a million people are already displaced, and 250,000 civilians have fled their homes during weeks of violence. Government forces, rebels, rival tribes and UN peace-keepers all are part of the story. The Financial Times' Matthew Green is in Goma in the eastern part of the country.
