M23 rebels have attacked Goma with heavy firing, killing and injuring many while forcing countless others to flee

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.

Rebels backed by Rwanda captured more towns in eastern Congo on Wednesday, as fighters moved beyond the key city of Goma in an apparent attempt to expand their control in the conflict-battered region.
