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.

Goma remains “under occupation” by Congo’s M23 rebels and the ceasefire they announced has been broken as their forces engage in heavy fighting along the main route to South Kivu’s main city Bukavu.

The Rwanda-backed rebels who seized eastern Congo's key city of Goma announced Monday a unilateral ceasefire in the region for humanitarian reasons, following calls for a safe corridor for aid and hundreds of thousands of displaced people.
