Security forces fired tear gas as Sudanese protesters marched in the capital Khartoum on Sunday against the country's military leadership, holding it responsible for an outbreak of violence in Blue Nile State.
More than 30 people were killed and 100 injured in tribal clashes that started last week between the Hausa and Fung tribes in the southeastern state, close to the border with Ethiopia, according to Sudanese officials and the United Nations.
