A rebel group that claimed to have captured the city of Goma in the eastern Democratic Republic of Congo last week has called for an immediate humanitarian ceasefire, after fighting with the Congolese military has left hundreds of people dead.

The rebels say they will not seize any further territory but will protect their positions.

The city of 2 million people is at the heart of a region home to trillions of dollars in mineral wealth and remains in rebel control.
