Despite child labour being illegal, the Burkina Faso government overlooks the use of children in mining and extracting gold. It’s willingness to overlook the use of child labour is based on its dependency on gold exports for revenues. Children are sometimes pulled from school to work alongside with their parents to earn money for the family.

To Maintain Supply of Sex Slaves, ISIS Pushes Birth Control.
New York Times.
Girls from religious and ethnic minority groups are captured, bought and sold by Islamic State (IS) members. The girls are repeatedly raped and given birth control to ensure the girls are not pregnant while the girls are bought, sold, or passed around. The girls are given oral or injectable contraception, sometimes they are given both. To ensure the girl is not pregnant, they are taken to the hospital to test for HCG hormone, which is indicative of pregnancy if it is present. If she is not pregnant, the captors continue to rape the girl or sell her to other captors for similar purposes.
