Madnodje Mounoubai, a spokesman for the U.N. mission in Congo, said the wounded were flown for treatment to neighboring Republic of Congo after Thursday's attack.
Mounoubai said a small U.N. unit was deployed to Dungu after fighting started earlier this month between the Enyele and Munzale tribesmen reportedly over farming and fishing rights.
More than 100 people have died and more than 50,000 have fled to Brazzaville in the neighboring small country Republic of Congo, Mounoubai said.
