ANSWER: South Sudan
Explanation:
South Sudan's President Salva Kiir has signed a peace deal with rebels after a threat of sanctions from the UN. He told those gathered for the signing ceremony in the capital, Juba, that he had "reservations" about how the mediation was conducted and some of the clauses in the compromise deal. Rebel leader Riek Machar signed the deal last week but Mr Kiir refused. It is meant to end months of brutal civil war and would see Mr. Machar return as Vice-President.
