Three years of conflict in #SouthSudan have left 4.8 million people food insecure, and the UN Human Commissioner for Human Rights has warned that the country “teeters on the brink of a disaster.” @UnitedNations agencies including @UNICEF are providing life-saving #humanitarian aid, such as food to treat malnutrition, as pictured above. A #UNICEF nutrition officer in South Sudan told us he chose this work because, “I wanted my work to produce results and to feel that I was contributing to improving people’s lives.” Visit unicef.org to learn more.
