Africa, the world's most impoverished continent, continued to suffer the world's most pervasive violence during 2000 and in early 2001. Nearly 3 million Africans became new refugees or were newly displaced within their own countries during 2000. New population upheavals last year and in early 2001 occurred in Congo-Kinshasa, Burundi, Sudan, Eritrea, Angola, Sierra Leone, Guinea, Liberia, Nigeria, Somalia, Uganda, and Zambia.
