Earlier, a UN mission investigating human rights abuse in South Sudan reported that gross violations of human rights had been committed on a massive scale.
The report “underscores the level of atrocities committed by all sides” and the need for “a special -or hybrid- tribunal, with international involvement, Ban said.
Ban, who visited South Sudan last week, said that “many thousands of South Sudanese have been killed, atrocities have been committed by both sides, more than a million people have been displaced and nearly 5 million more need humanitarian assistance”.
During the visit, the UN chief met with the country’s President Salva Kiir and rebel leader and former Vice President Riek Machar and warned them that they would “inevitably be the subject of international investigations regarding the extent of their knowledge of war crimes and crimes against humanity committed by subordinates under their authority” if they failed to stop fighting.
South Sudan gained independence from Sudan in 2011 after years of civil war.
