"Up to this morning we have found more than 40 bodies, all of them civilians, in the latrines," Teddy Kataliko, the head of civil society in the Beni region where the attack took place yesterday, told AFP.
"Teams from the Red Cross and the police are searching to see if they find other victims." The attack, which has been blamed on Ugandan rebels, has also left "dozens" of people seriously wounded, he said.
The UN's special force in DR Congo used helicopters yesterday to fire on the rebels and help government troops retake Kamango after the attack.
ADF-Nalu stands for Allied Democratic Forces-National Army for the Liberation of Uganda and is considered the only Islamist organisation in the region.
In July the Congolese army battled the ADF-Nalu rebels to take control of the Kamango region, but the fighting had sent tens of thousands of people fleeing for safety in neighbouring Uganda.
The mission helped bring down the M23 rebel movement last month, which was suspected of receiving support from Rwanda and Uganda, something both countries deny.
