South Sudan: Aid to refugees 'race against time'

Aid agencies working in northern South Sudan are worried about refugees from Sudan's war-torn Blue Nile State who are reaching under-resourced camps in increasingly poor health. In recent weeks over 35,000 people have flocked to a site 50km from the border known as Kilometre 18 (KM18) by aid agencies - the distance to the nearest refugee camp (Jamam) holding over 30,000 people.
