An independent investigation released Tuesday, Nov. 1, 2016, of attacks in July on a U.N. compound in South Sudan housing 27,000 displaced people, and a private compound not far away housing U.N. staff and aid workers, is sharply critical of the U.N. peacekeeping mission's leadership and the response by troops from China, Ethiopia, Nepal and India.
