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.

After capturing Goma, the main city in North Kivu province, last week, the M23 and Rwandan troops launched a new offensive on Wednesday in a neighbouring province.
