GENEVA (Reuters) -The United Nations rights chief urged on Friday for warring sides in South Sudan to pull back from the brink, warning that the human rights situation risks further deterioration as fighting intensifies. "The escalating hostilities in South Sudan portend a real risk of further exacerbating the already dire human rights and humanitarian situation, and undermining the country's fragile peace process," said the U.N. High Commissioner for Human Rights Volker Turk. (Reporting by Olivia Le Poidevin; editing by Matthias Williams)
