Over a half million foreign workers fled the violence in Libya last spring during the fall of Tripoli. Most migrants were from Egypt, Tunisia or sub-Saharan Africa. Thousands came from a single town in the West African nation of Ghana. That town is called Nkoranza and it's nearly 3,000 miles away from Libya's capital of Tripoli.
