The renewed violence that residents reported in and around the region’s largest city of Goma – which the M23 rebels control – was the biggest threat yet to ongoing peace efforts by both the Gulf Arab state of Qatar and African nations in the conflict that has raised fears of regional warfare.

Goma resident Amboma Safari recounted how his family of four spent the night under their bed as they heard gunfire and bomb blasts through Friday night. “We saw corpses of soldiers, but we don’t know which group they are from,” Safari said.

In the second city of Bukavu, which the M23 also controls, dozens of the armed Wazalendo local militia members who fight alongside Congolese forces marched for a few hours towards the local airport as they appeared to stage a challenge against the rebels. (Jamaica Gleaner/AP)
