South Sudan, located in the heart of Africa, is the youngest nation in the world; it gained independence from Sudan in July 2011. Two years later, a civil war broke out, pitting the ruling Sudan People's Liberation Army (SPLA) against the opposition; the conflict has since become a brutal tribal war. The “Agreement on the Resolution of the Conflict in the Republic of South Sudan,” signed by both factions in August 2015, brought but temporary peace, with fighting flaring up again since last summer. Meanwhile, ordinary citizens of South Sudan suffer hunger and are caught in the fighting. The UN estimates that there are 1.7 million Internally Displaced People (IDPs) in the country, 75 percent of whom are struggling to survive in the three states hardest-hit by conflict, Unity, Upper Nile and Jonglei.
