SLAVERY: Shocking photos of Nigerians and other Africans held captive and sold as slaves in Libya [PHOTOS]

Most of them end up being captured and sold as slaves. While in captivity, they are kept in dehumanizing conditions and maltreated. Some are sold so that their body organs can be harvested and sold, while some end up being killed. A lot of them are used as sex slaves, including the men who get raped by other men. There are 1 to 2 auctions every month where buyers come to assess captives and make their choice.

The crime against humanity was brought to light after CNN published the report of an investigation they carried out last week. A CNN team traveled to Libya and witnessed a dozen men being sold for as little as $400 each. And the slave traders do not lack men and women because according to reports, thousands of migrants have arrived in Libya in recent years in a desperate bid to travel the central Mediterranean route to Europe. The International Organization for Migration estimates there are currently between 700,000 and a million migrants stuck in the country.

Since the CNN report, Libya has opened an investigation into the slave markets. The probe is being overseen by the government's Anti-Illegal Immigration Agency.
