UNHCR, the UN High Commissioner for Refugees, has warned on Wednesday that the situation for refugees fleeing Blue Nile and South Kordofan states of South Sudan had become critical, and humanitarian efforts in South Sudan are close to breaking point.
More than 200,000 people displaced into South Sudan and Ethiopia.UNHCR chief Antonio Guterres said the combination of difficult and dangerous conditions in South Sudan and the huge numbers of refugees arriving in Upper Nile and Unity states are severely stretching operations.
He said many newly arriving refugees are already dangerously malnourished.
Mr Guterres added that the threat from water-borne disease is high.
Large refugee populations are in locations that are dangerous.
Flooded roads block access and the possibility of relocating people elsewhere.
UNHCR has appealed to governments and the public to help by donating additional funds for the Sudan refugee crisis.
