President Bush has called for an end to “ethnic cleansing” in Sudan, south of Egypt. The State Department says 30,000 people have been systematically killed, while a million more have become refugees. Since independence from Britain in 1956, 30 million Sudanese have been engaged in a civil war that has left two million dead. Now, the Muslim government is arming nomadic Arabs in the western part of the country who are, in turn, systematically destroying villages of black Africans who are also Muslims. The failure of the United Nations to intervene recalls the genocide in Rwanda 10 years ago, and promises that it would never happen again. Warren Olney looks at this developing humanitarian crisis with experts in African affairs, including historians and human rights activists, a UN spokesman and a State Department advisor.

Writing in The New Yorker, Burkard Bilger recounted the research of "anthropometric historian" John Komlos, who’s doing research at the University of Munich.
