Selling sex to Senegal's gold diggers

Gold was discovered in Senegal half a decade ago. Since then, the region of Kedougou, near the border with Mali, has changed drastically.

One of the places more radically affected has been Diabougou which until recently was a tiny village and now is home to thousands of informal miners.

But along with wealth, gold has brought prostitution to the very traditional and remote area.

The BBC found that more than 80 young Nigerian girls are forced to sell sex in Diabougou. They were trafficked to Mali, and eventually crossed the border to Senegal, where the BBC's Network Africa's Maud Jullien met some of them.
