Several dissident soldiers in the Democratic Republic of Congo (DRC) have been killed in a clash with government forces in the east of the country.
The UN says the death toll from Wednesday's fighting is not clear. Some reports speak of 18 insurgents killed.
DRC government forces say they were attacked by troops loyal to dissident Gen Laurent Nkunda north of Goma, in North-Kivu region.
The situation in the east remains highly volatile, correspondents say.
This is despite a 2003 ceasefire which ended a five-year conflict.
The rebels have occupied the Rutshuru hills near the Rwandan border since early December.
DR Congo is attempting a transition to democracy and this month installed an elected president, Joseph Kabila, for the first time in 40 years.
