The Rwanda-backed rebels who captured eastern Congo 's key city of Goma sought to reassure its residents Thursday, holding a stadium rally and promising safety under their administration as they try to shore up public support amid growing international pressure.

The M23 rebel group have captured the city of Goma in the eastern DRC in a major escalation of a drawn-out conflict.

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.
