Clashes have reignited in Uvira, eastern Democratic Republic of Congo, between government forces and M-23 rebels. The escalation comes despite the group’s recent announcement of withdrawal after capturing the strategic town on December 10. UN agencies report that the offensive has forced tens of thousands to flee into neighboring Burundi, overwhelming humanitarian aid capacity. The Congolese government accuses the rebels of regrouping in nearby hills and reiterates allegations of Rwanda’s support for the armed group.
