Democratic Republic of Congo's M23 rebels are moving south towards Bukavu, the capital of South Kivu province, in what appears to be an attempt to expand their area of control in the country's east after capturing the city of Goma.

Rwanda-backed rebels claimed on Monday they captured eastern Congo’s strategic city of Goma, the hub of a region containing trillions of dollars in mineral wealth that remains largely untapped.

The eastern DRC city of Goma was seized by M23 rebels and their Rwandan allies on 26 January. Residents have emerged to count the dead and make sense of the fast-moving offensive.
