GOMA, Democratic Republic of Congo (Reuters) -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,

Congo's government on Tuesday described the unilateral ceasefire declared by Rwanda-backed rebels in eastern Congo as “false communication,” while the United Nations noted reports of heavy fighting with Congolese forces in the region.

Rwandan-backed M23 rebels captured the mining town of Nyabibwe in eastern Congo’s South Kivu province, violating a ceasefire they declared earlier this week, according to NBC News. The rebels now advance toward Bukavu, raising fears of further conflict after seizing the city of Goma last week.
