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.

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.

In the last 48 hours, two U.N. peacekeepers from South Africa and one from Uruguay were killed and 11 peacekeepers were injured and hospitalized.
