JUBA: South Sudan’s President Salva Kiir yesterday promised aid agencies safe access to hunger-stricken civilians, a day after his government declared a famine in parts of the war-ravaged country. South Sudan has been mired in civil war since 2013 and the United Nations said on Monday it was unable to reach some of the worst hit areas because of the insecurity. “The government will ensure that all the humanitarian and developmental organizations have unimpeded access to the needy population across the country,” Kiir said in a speech to parliament.
