The probe into this and other attacks on UN peacekeepers and their bases in eastern Congo will assess "overall preparedness and response to the events and provide recommendations on how to prevent such attacks."
UN investigators, accompanied by two military officers from Tanzania, will travel to Congo later this month and visit areas in countries surrounding the Great Lakes region.
The December 7 attack on a UN operating base at Semuliki also injured 43 peacekeepers, while one remains missing. The UN blames the assault on rebels from the Allied Democratic Forces, based around the mountainous Congolese-Ugandan border.
