South Sudan President Salvar Kiir has reinstated his one-time ally turned foe Riek Machar as the country’s vice president to stem a fresh civil war.

His decree came on Thursday soon after a UN Monitoring report highlighted atrocities committed by troops loyal to both Kiir and Machar in a conflict that has been running since 2013.
