ISIS

A German father struggles to find and bring home his young daughter, taken by his ex-wife when she went to Syria five years ago with her new husband, an ISIS fighter.

Kurdish Syrian authorities have tried 7,000 ISIS suspects in a justice system that bans torture and the death penalty. Some of the judges are women, which comes as a shock to ISIS fighters on trial.

ISIS has radicalized people around the world. But even with one of the world's largest Muslim populations, India has had very few cases of radicalization — until recently. Most cases are in the south.

Women kidnapped by ISIS five years ago are now being freed. But the Yazidi community does not allow children born in captivity of militant fathers to return with them.

"The women and children who have been raised on the mentality of ISIS and terrorism need to be rehabilitated," an official warns. "Otherwise, they will be the foundations of future terrorism."
