By Sonia Rolley (Reuters) -When M23 rebels swept into the Congolese city of Goma this week, world powers urged them to immediately withdraw. Instead, the Rwanda-backed insurgents are intent on showing they can restore order and govern.

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 Democratic Republic of Congo's electoral body has accused the Rwandan army and M23 rebels of looting polling office facilities in Goma, a city in eastern Congo.
