The president and vice president of South Sudan have urged the loyalists fighting on their respective behalfs to halt hostilities after violence has threatened to drag the country back into an all-out civil war. The initial fighting broke out four days ago in the capital of Juba and has killed hundreds of people as soldiers fight on behalf of President Salva Kiir and Riek Machar, the former rebel leader who became vice president to end the previous civil war.
