Attackers in Central African Republic ambushed a convoy of UN peacekeepers from Cambodia and Morocco, killing one Cambodian soldier and wounding six other peacekeepers, Cambodian officials said Tuesday.
Three Cambodian soldiers and one Moroccan peacekeeper were also reported missing after Monday's surprise assault and may have been kidnapped, the officials said.
It was not immediately clear who was responsible.
Central African Republic has been embroiled in chaos since 2013, when rebels overthrew the nation's president.
The United Nations launched a peacekeeping mission in the country in 2014 and now has more than 12,000 troops deployed to protect civilians from unprecedented deadly violence between Christian and Muslim factions.
Cambodian Prime Minister Hun Sen announced news of the attack in video remarks published on his official Facebook page that came as he inaugurated a new building in Cambodia's eastern Tboung Khmom province.
He said the Cambodians were part of an engineering unit that was helping to build roads, bridges and other infrastructure.
The ambush took place Monday morning as the Cambodians were on the way back to their base with an escort of Moroccan soldiers. One Cambodian was wounded in the ambush and three more were missing, Hun Sen said.
Chhum Socheath, a spokesman for the Cambodian National Defense Ministry, said five Moroccan peacekeepers were also wounded in the violence, and that one was missing.
The slain peacekeeper was a captain and his body was being repatriated home, he said, adding that Cambodia has deployed a total of 12 Cambodian soldiers to the central African nation in recent months.
Central African Republic has faced sporadic violence and instability after years of sectarian fighting, with some 890,000 people displaced inside the country and into neighboring Cameroon, according to the UN.
Over the weekend, four international aid groups said they would temporarily withdraw their workers from parts of northern Central African Republic because of increasing attacks targeting them. The four — Solidarites international, Intersos, Danish Church Aid and Person in Need Relief Mission — were to move to the capital, Bangui.
