A U.N.-run radio station says 47 police officers have been killed amid fighting in northern Congo.

Villagers from two different communities were involved in a fishing dispute and the police tried to intervene Thursday.

The officers also were attacked, according to Col. Joly Limengo, the police inspector for Equateur province.

The fighting took place between residents of Iyele and Muzaya, he told The Associated Press. Limengo said among the villagers there were ex-combattants from rebel movements and those demobilized from the army.

U.N.-run Radio Okapi said 47 officers were killed in the violence along with an unspecified number of civilians. Authorities and police on Friday confirmed the violence but did not know how victims there were.
