About 19 people have been killed in an attack by an armed group on two Congolese villages, a local youth leader said Saturday. According to dpa, the militia known as Mai Mai Mazembe, most of whose members belong to the Nande ethnic group, attacked Hutus living in the villages of Kaghala and Rushaki in a north-eastern province on Friday, Philippe Manizaye said. Six people were reported injured. The army confirmed the attack, without giving a death toll. The reasons for the attack were not known.
