The ISIS militants were arrested in a 10-day operation, during which five trenches have also been discovered and 16 mobile phones have been seized.

As part of the operation, 50 percent of the camp was searched and 121 suspects, including 15 women, were arrested, 14 of whom are ISIS militants.

More than 65,000 families of ISIS militants, 94 percent of whom are women and children, live in al-Hol camp, and more than 100 people have been killed since the beginning of last year, according to UN figures.

Security experts warn of the rise of another generation of ISIS from Camp Hall.
