 Meanwhile, the United Nations Refugee Agency warned on Tuesday all for the displacement of people from Sudan after thousands streamed into neighboring Chad and South Sudan, despite a ceasefire between the two, warring Sudanese generals battling for control of the country. The fighting has plunged Sudan into chaos, pushing the African nation to the brink of collapse. Since the clashes erupted, at least 20,000 Sudanese have fled into Chad and some 4,000 South Sudan refugees who had been living in Sudan have returned to their home country. UNHCR spokeswoman Olga Saradell said, Spokesman Jens Lek of the UN office of the Ford Accordination of Humanitarian Affairs said it has been forced to reduce its footprint because of the fighting. So far, the most significant cross-border movements in the region have been of Sudanese fleeing to Chad and South Sudanese refugees returning to South Sudan. While we have also received reports of people starting to arrive in Egypt, exact numbers are not available at this point. Some of the population movements we expect to observe in the coming days include outflows of new Sudanese refugees to neighboring countries, returns of refugees who are being hosted by Sudan, and movements of other refugees being hosted by Sudan to other neighboring countries. UNHCR is working closely with partners and governments in the regions to assess the needs of the newly arrived and prepare a joint.
