Rabat – The MI-8 helicopter was on a routine operation carrying Ethiopian peacekeepers on rotation from Kadugli to Abyei when it crashed on the Sudan-South Sudan border.
The UN said in a statement that ten passengers on board were injured, while three others are in critical condition.
The UN added that the cause of the crash is still unknown.
Ethiopia is the only contributor with around 4,500 personnel mobilized for ensuring peace and security in Abyei.
Both Sudan and South Sudan are in dispute over the oil-rich Abyei region.
