Rwandan-backed M23 rebels in Democratic Republic of Congo are seeking to advance south towards Bukavu, the capital of South Kivu province, in an attempt to expand their area of control in the country's east after capturing the city of Goma.

Bodies are decomposing on the streets of Goma that have not yet been collected, with hundreds of thousands displaced in the region after fighting between Rwanda-backed rebels and Congolese forces.

Rwandan-backed M23 rebels say they are now in control of the key eastern Congolese city of Goma. Their fighters continue to claim more territory in one of the world's most mineral-rich territories.
