More than 100,000 people have fled violence in Sudan to neighbouring Chad and the numbers could double in the next three months, the U.N. refugee agency said on Thursday.
The near seven-week conflict has pushed Sudan into a humanitarian crisis and turned one of Africa's greatest cities - the three-part capital of Khartoum, Omdurman and Bahri on the confluence on the Blue and White Niles - into a war zone.
