The AIR reported that civilians had taken refuge in the UN base, adding, the rebels from the second-largest ethnic group, the Nuer, stormed the military post in Akobo in Jonglei state, targeting civilians of the majority Dinka ethnic community. Around 43 Indian peacekeepers along with six UN police advisers and two civilians were present in the base when the gunmen numbering 1,500-2,000 stormed it, the report added. The United Nations Mission in South Sudan, UNMISS, issued a statement, strongly condemning the assault.
