_________________________________________________________ The White House urged the country's president and its former deputy to assume their responsibilities and prevent further needless suffering. Chris Stillwalker reports. "This rises to more than 600 million dollars, a total amount of the United States has so far provided in humanitarian assistance to South Sudan. The White House says the South Sudanese are suffering because of the inability of the country's leaders to put their people's interests above their own. A power struggle between its president Salva Kiir and his former deputy Riek Machar has plunged the country into renewed warfare, leaving thousands dead and nearly two million refugees." ________________________________________________白宫已经督促该国总统和前副总统承担起责任,避免造成更多的痛苦.克里斯 斯蒂尔沃克尔(Chris Stillwalker)报道."迄今为止美国向南苏丹提供的人道主义援助总额已高达6亿美元.白宫表示,由于南苏丹领导人未能将人民利益放到首位,人民正遭受痛苦.总统萨尔瓦基尔与他前任副总统瑞克马查尔之间的权利争斗致使整个国家陷入新的战争,导致数千人死亡,近两百万人沦为难民."
