UN urged to stop 'ethnic cleansing' in South Kordofan

Human rights activists are lobbying the United Nations to stop ethnic-related violence in the Sudanese province of South Kordofan.

Sudanese troops have been battling former rebels who fought with the South in Sudan's civil war.

On a visit to the UN's headquarters in New York an Anglican Bishop claimed that Khartoum was carrying out an ethnic cleansing campaign.
