Calm gradually returns to Kibumba, a town 20 km north of the city of Goma in the east of the Democratic Republic of Congo, after a week of intense fighting between the Congolese army and M23 rebels. The latter are said to be supported by the Rwandan army, according to Congolese authorities. According to the UN, more than 72,000 civilians had fled and are now timidly returning to their villages, but apprehension and fear remains, given the borders with Rwanda. IMAGES AND SOUNDBITES
