Goma, Democratic Republic of the Congo - Residents and M23 supporters shout slogans as they celebrate the takeover of the city by M23 fighters at the governor's office compound in Goma, after the M23 (March 23 Movement) rebel group launched a large-scale offensive in eastern DRC.

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.

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.
