who were raped and burned alive with their children - with international arrest warrant issued against leader Rwandan-backed rebels appeared to violate a unilateral ceasefire they declared this week by rampaging through new parts of the Democratic Republic of Congo overnight. The M23 rebels launched a fresh offensive, clashing with the Congolese forces in the early hours of Wednesday before they successfully seized Nyabibwe, a crucial mining town in South Kivu province.
It comes as the UN said the battle for the key city of Goma, which M23 and Rwandan troops took over last week, has already left at least 2,900 people dead - including scores of female prisoners who were raped and burned alive during a jailbreak.
The city was plunged into chaos, with bodies lying in the streets as the rebels executed a rapid advance.
