New York - A Moroccan peacekeeper who was missing in the Central African Republic after an ambush has been found dead, the UN confirmed Thursday.

Four Cambodian peacekeepers working in the country were also killed Monday in the guerilla ambush on a UN patrol.

The UN's head of peacekeeping, Jean-Pierre Lacroix, will travel to the capital city Bangui to take part in a memorial ceremony on Friday, the spokesman for the UN Secretary General Antonio Guterres said.

The UN called the ambush, which also left nine Moroccan troops and one Cambodian soldier injured, the "biggest attack in the CAR so far."

Seven of the wounded soldiers are being treated in Bangui, five for minor injuries and two for more severe but non-life-threatening injuries.

The remaining three are at a UN mission hospital in the city of Bangassou, 47 kilometres east of Bangui.

Eight fighters from the mainly Christian anti-Balaka militia were killed in the firefight and appear to have initiated the attack on the convoy near Bangassou.

The Central African Republic is one of the poorest countries in the world. The diamond-rich but poverty-stricken nation has been in crisis since late 2012, when inter-religious violence broke out between Muslim and Christian rebel groups.
