TEHRAN, Young Journalists Club (YJC) - U.N. spokesman Stephane Dujarric said 10 peacekeepers also were injured and one was missing after Wednesday's operation that targeted Allied Democratic Forces rebels.
The Security Council's statement said seven of the peacekeepers who were killed were from Malawi and one was from Tanzania.
A U.N. official said U.N. and Congolese forces were attacked while conducting operations to dislodge the rebel fighters from a stronghold in Kididiwe, near the regional capital of Beni. The mission succeeded and a number of rebels were captured, the official said, speaking on condition of anonymity because he was not authorized to discuss the matter publicly.
Congo's volatile east is home to many armed groups vying for control of the mineral-rich region, and the Allied Democratic Forces and Mai-Mai rebel groups are especially active in the Beni area.
The Security Council called on all armed groups to stop the violence immediately and lay down their arms, echoing an earlier statement from U.N. Secretary-General Antonio Guterres' spokesman.
The U.N. chief and the council urged Congolese authorities to apprehend and bring to justice the perpetrators of attacks on civilians, national security forces and U.N. peacekeepers.
