M23 fighters on Friday advanced further on several fronts in DR Congo's volatile east as international pressure mounted on Rwanda to stop backing the armed group and halt the fighting.
The M23 -- which is supported by some 4,000 Rwandan soldiers according to UN experts -- took control of the South Kivu provincial capital Bukavu on Sunday, just weeks after capturing Goma, the capital of North Kivu and main city in the Democratic Republic of Congo's mineral-rich east.
