Shocking photos and video of filthy ISIS jail where sex slaves were raped and tortured by terror group

Shocking footage has emerged revealing the hell-like prison used by Islamic State militants to rape and torture women.

The filthy cells uncovered by rebel fighters after defeating ISIS in Manbij, Syria show brutal torture instruments, sex drugs, dirty mattresses, dog bowls on the floor, contraceptives and desperate messages scrawled on the walls.

The dark dungeon contains ten small cells behind iron doors where the women held captive by ISIS were constantly raped .

One message scribbled on the wall in Arabic says:

“God, I have wronged myself, and no one forgives sins but you. Forgive me, you are forgiving and merciful.”

The Kurdish-led Syrian Democratic Forces, backed by the U.S military made the shocking discovery of the cells and one of their leaders Ibrahim Al-Mohammed told the Arab24 agency:

''We discovered an Islamic State group prison for women, with rooms for groups as well as solitary prisoners. We found the worst, most violent torture tools, and may God curse them."

Another Kurdish forces group leader Omar Mazerli said:

"We found various kinds of pills, including sexual stimulation, contraceptives and narcotic pills which were used by the Islamic State group for torture. They have very strange ways. This place was very hard to find and it is well hidden, but we got here with God's will and the efforts of the Military Council."

The capture of Manbij by the Syrian Kurdish forces is the biggest defeat for the terror group in Syria since July 2015, when they lost the town of Tal Abyad on the border with Turkey.
