Thousands of families have been displaced by violence in eastern Congo, where Rwanda-backed rebels last month seized the key city of Goma in a blitz offensive in the mineral-rich region.

Rwandan-backed M23 rebels have seized control of a mining town in eastern Democratic Republic of Congo's South Kivu province, eight sources said on Wednesday, in an apparent violation of a unilateral ceasefire they declared this week.

The group has made dramatic advances in Congo’s North Kivu province since re-emerging as a force in late 2021. It has repeatedly denied receiving support from Rwanda. And the government in Kigali equivocates about its support for the rebels.
