Rwandan-backed rebels M23 launch new offensive in DRC

Clashes break ceasefire days before Rwandan and Congolese presidents attend crisis summit

Rebels of the M23 armed group and allied Rwandan forces have launched a new offensive in the eastern Democratic Republic of Congo (DRC), days before the Rwandan and Congolese presidents are due to attend a crisis summit.

The UN said the battle for the key city of Goma, which M23 and Rwandan troops seized last week, had left at least 2,900 people dead - far higher than the previous death toll of 900.
