Violence in eastern Democratic Republic of Congo has left more than a dozen people dead in three days, military and local sources said on Sunday.
Over 120 militias roam the country`s volatile east, and there are frequent attacks on civilians.
Two soldiers were among those killed since Friday.
A military leader in North Kivu province said Sunday: "We have just lost a brave soldier killed in an attack on our position in the northern outskirts of the city of Butembo by Mai-Mai militiamen".
The leader, who did not wish to be named, said two members of the militia were killed.
On Sunday in northeastern Ituri province "six gold miners were killed and decapitated by rebels from the CODECO group", Prince Kaleta, civil society president in Lodjo, Ituri told AFP.
CODECO -- the Cooperative for the Development of the Congo -- is a political-religious sect that claims to represent the interests of the Lendu ethnic group.
It is considered one of the deadliest militias, blamed for ethnic massacres in Ituri.
