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 United Nations says Rwanda-backed rebels captured large parts of eastern Congo’s largest city of Goma including its airport.
