The UN refugee agency said Tuesday 25 September that fresh air and ground attacks in Sudan's South Kordofan state are causing a renewed population influx to South Sudan. 'About 100 refugees a day are arriving in the border town of Yida, in Unity state,' a spokesperson said, adding that the 'refugees are in poor health and without any belongings.' Some refugees told UNHCR they had also fled because of acute food shortages in South Kordofan. Many said they planned to build a shelter in Yida refuge camp before returning across the border to fetch family members.
