An estimated 226,950 South Sudanese refugees have fled to Sudan since December 2013, the United Nations Office for the Coordination of Humanitarian Affairs (OCHA) said in a report citing refugee agency UNHCR.
According to the report, the influx of South Sudanese refugees came as a result of the conflict and the deterioration of food security.
It is estimated that nearly 69,000 people have arrived to various states in Sudan since the beginning of this year until 22 May.
The report said UNHCR and partners are currently updating their response plan to cope with the newcomers.
The report said that humanitarian organizations are continuing to provide humanitarian assistance and basic services for the South Sudanese refugees in Kour Omer camp, while the World Food Program plans to distribute shares of food material for this month, pointing out that an estimated 28,428 refugees at Kour Omer camp will receive food aid in May.
