Two million people have been displaced from their homes by violence in the Kasai province of the Democratic Republic of Congo, where 80 mass graves have recently been discovered. Not coincidentally, huge deposits of coltan and other precious minerals have been found in the region, said Kambale Musavuli, of Friends of Congo. The killings are widely blamed on soldiers of President Joseph Kabila, who refuses to step down despite having used up his two terms in office. “This is the same area where King Leopold II of Belgium caused the death of millions of Congolese, a hundred years ago,” said Musavuli.
