New York, Dhu-AlQa'dah 07, 1437, August 10, 2016, SPA -- At least 70,000 South Sudanese have fled to neighbouring Uganda since renewed violence broke out last month in the war-torn country, a top UN official said Wednesday, according to dpa. UN humanitarian affairs chief Stephen O'Brien, who visited South Sudan in early August, warned of an "enormous and complex humanitarian crisis" facing the country, where 1.6 million people are internally displaced and some 4.8 million are severely food insecure. "Sadly, in the past year, the humanitarian situation has significantly deteriorated, including in areas that were relatively stable, and displacement and hunger are now widespread across the country," O'Brien said. He noted that at least 70,000 people have fled to Uganda since July, an increase even from last week's UN estimate of 60,000. --SPA 23:30 LOCAL TIME 20:30 GMT www.spa.gov.sa/w
