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.

The alliance of rebel groups in eastern Democratic Republic of Congo have declared a humanitarian ceasefire starting on Tuesday. In a statement, the group - which includes the Rwanda-backed M23 rebels - cited "humanitarian reasons" for the ceasefire, after it has been capturing territory in eastern parts of the country.
