The rebels, thought to be members of the Islamic State-linked Allied Democratic Forces (ADF), abducted the group in a village in Ituri province on Sunday evening, according to Dieudonne Malangayi, acting chairman of the chiefdom of Walese Vonkutu.
The rebels erupted into the Bundingili area where the village is located, and kidnapped "all the civilians who were there, men, women and children," he said by phone.
More than three kilometres away in the bush, the militants "freed the men, women and some young children," but kept the 11 other children.
