When President Barack Obama outlined his plan last week for fighting the so-called Islamic State group last week, he described that the terrorist group was responsible for many crimes including sexual violence.
"They enslave, rape, and force women into marriage," Obama said.
Last month, the United Nations estimated that the group forced some 1,500 women, teenage girls and boys into sexual slavery.
Former CIA intelligence analyst Nada Bakos explains that it's a disruptive force that helps these fighters gain control of a local community.
