Members of the Allied Defense Forces rebels attacked three villages around the town of Beni, more than 300 kilometres north of Goma, the provincial capital, according to the coalition from North Kivu province.
On his Twitter account, Martin Kobler, head of the UN peacekeeping mission in Congo, condemned the attack and called for Congolese forces and the UN peacekeepers to respond. He said troops from both forces were in the area today.
Eastern Congo is home to a myriad of armed groups and militias, many vying for control of the region's vast mineral resources. The UN peacekeeping force is authorised to battle the rebels groups but has been criticised for doing too little to protect civilians.
