Residents in eastern Congo’s largest city, Goma, woke up on Monday morning uncertain about who is in control of the city, which Rwanda-backed rebels claimed to have captured.

The M23 militia, funded and directed by Rwanda, said it took the city of Goma, terrifying its people, many of whom sought shelter there after fleeing the rebel advance.

Rwanda has been urged to withdraw its advancing troops from the outskirts of Goma, a mineral-rich city in the Democratic Republic of Congo (DRC).
