More than 105,000 refugees have crossed the border between Sudan’s Blue Nile state and South Sudan’s Upper Nile state since November, 2011.

Most flee on a moment’s notice, bringing only what they can carry, and sometimes nothing more than the clothes on their backs. Some arrive ill or injured, and many have gone hungry along the way.
