A Ugandan rebel group killed at least 10 people and abducted six others during attacks on two villages in eastern Congo, a rights organization said on Saturday. Rebels from the Allied Democratic Forces (ADF) carried out the attacks in the provinces of North Kivu and Ituri, a leading activist of the Congo-based human rights organization CRDH said. A team was investigating the killings on Friday, coordinator Jean-Paul Ngahangondi told dpa, adding that the number of victims could increase.
