The victims were killed during a recent UN operation.
Demonstrators in the Central African Republic have laid the bodies of some of those killed in recent violence outside the UN mission building in Bangui.
At least 21 people were killed during a UN operation in the mainly Muslim PK5 neighbourhood, during which peacekeepers and the army fought armed groups.
Officials are unsure whether the victims were caught in the crossfire or deliberately targeted.
