Children study outside a classroom tent at a school in the PoC (Protection of Civilians) site inside Bor UNMISS base. There are 702 pupils at the school, which is run by volunteers. The PoC site is currently providing sanctuary to approximately 2,500 internally displaced people (IDPs), predominantly from the ethnic Nuer group. South Sudan's Jonglei state was the scene of fierce fighting after conflict erupted in the country in mid-December 2013, with thousands of civilians seeking shelter at the UN base in the capital, Bor.
