Amnesty International said in a report that UN peacekeepers and South Sudanese authorities failed to take adequate action despite warnings weeks before insurgents raided a village and killed more than 200 people earlier this year.

The official death toll is at least 213, including 130 town residents, 76 security personnel and seven foreign nationals. According to the rights group, the UN mission (UNMISS) knew an attack on Abiemnom, a remote area near the border with Sudan, was likely but only reinforced the roughly three dozen peacekeepers based there after it occurred. The UN Security Council renewed UNMISS’s mandate in April while reducing its authorized troop ceiling from 17,000 to 12,000. UNMISS spokesperson Priyanka Chowdhury said in a statement that the mission did its best with limited resources to provide protection and medical care to the roughly 2,500 people who sheltered at a protected area established in anticipation of the attack.
