Operations for Sudanese refugees stretched-UNHCR
The situation for refugees fleeing Sudan's Blue Nile and South Kordofan states has become critical.
That is the assessment of Antonio Guterres, head of UNHCR, the UN refugee agency.
Mr. Guterres says with more than 200,000 people fleeing into neighbouring South Sudan and Ethiopia, humanitarian efforts in South Sudan are close to the breaking point.
The major pressure of this influx from Sudan is on South Sudan, says UNHCR, with 62,000 people in Unity State and 113,000 in Upper Nile State.
UNHCR says newly-arriving refugees are dangerously malnourished and, with the arrival of the rainy season, face the threat of water-borne diseases.
Most are in remote areas lacking even basic infrastructure, according to the agency, with children and teenagers making up more than 50 percent of the refugees in Assosa, Upper Nile State, and Unity State.
