Thousands of civilians - at least 13-thousand according to the United Nations Office for the Co-ordination of Humanitarian Affairs - have fled from the area of Ntulumamba, in the eastern Democratic Republic of Congo, where between July 9 and 10 thirty-nine civilians were killed in an armed attack. According to the same source, 90% of the around 15,000 inhabitants of the Kalonge district, around 70km from Bukavu, provincial capital of South Kivu, abandoned their homes seeking shelter in villages considered more secure. According to the OCHA, the displaced now count a total of 32,000, given that the new flow of civilians adds to two previous groups that fled their villages in the Kalonge area in February and April due to analogous episodes of violence against the population. The MONUC (UN Mission in DR-Congo) is conducting investigations to individuate responsibilities in the massacre of Ntulumamba, where unidentified armed men torched huts and homes, mainly killing women and children.
