Officials in the Democratic Republic of Congo say nine people, including several children, were killed when rebels attacked two villages in the east of the country.
Late on Monday Allied Democratic Forces (ADF) rebels used machetes to kill people in Oicha and Eringeti – two villages north of the city of Beni.
Local residents say the group had warned of imminent attacks but the motive is unclear.
Many hundreds of people have since fled the area.
The ADF has no clear political agenda but is reported to have recently formed a link with the Islamic State group.
