Rebels in eastern Congo's largest city, Goma, began a ceasefire on Tuesday and people rushed to bury some 2,000 victims of last week's battles for the city as they feared the spread of disease.

The Rwanda-backed rebels who seized a major city in eastern Congo have declared a unilateral ceasefire, citing humanitarian grounds. But, there was no sign of them giving up control of Goma at the heart of a region home to trillions of dollars in mineral wealth.

Nearly three thousand people have been killed in the city of Goma in the eastern Democratic Republic of Congo, according to the United Nations, after the provincial capital was captured by rebels following days of fierce fighting with the Congolese army.
