A United Nations Board of Inquiry says that it is highly likely that South Sudanese government forces supported an attack on a U.N. camp for internally displaced people in order to foster the ethnic reconfiguration of the northern city of Malakal.

The board's executive summary released Friday blamed a combination of factors, including the political situation, for the February attack which left some 30 people dead and 123 injured.

The board also found that the peacekeeping mission failed to effectively manage the crisis with some units failing to act and a lack of coordination among the mission's civilian, police and military components.

The summary recommended that the U.N. review the concept of Protection of Civilian sites to avoid the false expectation of protection when it may not be feasible.
