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.

The conflict escalated with the rebels' advance into Goma, which left bodies on the streets and drove hundreds of thousands of already displaced people to flee once again.

Rwanda-backed rebels who have captured eastern Congo’s largest city say they plan to take their rebellion to the capital and seek to gain political power
