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.
