Three young Yazidi women have bravely told their stories in the hope of dissuading impressionable young Muslim girls from joining the terror group in Syria and Iraq.
Three former ISIS brides have told of the daily horror they endured before escaping the terror group - including being raped five times a day and sold as sex slaves.
The young Yazidi women, Bushra, 21, Munira, 17, and Noor, 22, were abused on a regular basis including being tied up, gang-raped and burnt with cigarettes.
After escaping Iraq, the women were flown to the UK by international Charity AMAR, which helps people rebuild their lives following conflict.
They have bravely told their stories in the hope of dissuading impressionable young Muslim girls from joining the terror group in Syria and Iraq.
Bushra, who tried to kill herself after she was sold to the so-called Islamic State, said: "The man who had bought me took me to hospital.

"He told me he was going to rape me that same day, however ill I made myself. He took me home, tied up my hands and feet, and raped me.
"He raped me about five times a day. My sister was barely 14 when they raped her.
"I could hear her screaming but I couldn't do anything as I was tied up."
She also told of how one girl slit her wrists to escape the ordeal, with her body wrapped in a blanket and thrown out with the rubbish.
The three girls gave a talk in London to arranged by AMAR following the disappearance of 15-year-old Bristol schoolgirl Yusra Hussien last year.
She is one of 43 women who have left the country to join the terror organisation in Syria.
Three teenagers from City Academy, which Yusra attended, travelled to the capital to be at the talk.
Munira, another terror bride, told how she was first raped as a 15-year-old by a man four times her age.

She said: "We were held in a tiny room with a small window. They told us we were their sex slaves. They raped girls as young as six as well as adults.
"I was in a terrible mental state. I was devastated. I was alone. He raped me every day. Because of the constant rapes I bled, and my body was in agony.
"I used to cry every day. I missed my family and my little sisters."
And Noor, 22, said she was brutally attacked and burned with cigarettes after she tried to escape from the group.
She was captured in August last year.
"They began to choose the girls. The girls were shouting, screaming and vomiting," Noor told the students.
"He brought some honey. He would dip his big toe in honey, and put his toe in my mouth.
"He burned me with cigarettes, on my shoulders, my stomach and legs. I didn't even have the strength to speak after that.
"I couldn't stop thinking about my mum. I was in so much pain. I felt numb. I tried to escape. If I got caught and killed, then so be it.
"I just wanted to end this torture.
"He opened the door and six guards came in. Then he closed the door. Imagine a small girl between six old men - monsters."
Eighteen-year-old Bristol student Nasra Ahmed says she is in contact with Yusra and others who have joined the terror through social media.
She said: "They say they have a nice house, a husband, money, everything a 15-year-old would want."
"It is all lies," Noor replied, "they promise them a nice house, servants and a car but they lie again."
Another Bristol girl, 14-year-old Ikram Hassan, asked what advice they would give to people wanting to join ISIS.
Munira replied: "My message is, don't go. You will be raped and beaten and sold to other men. They are criminals."

The women have all now returned to Iraq but have been offered asylum in Germany, where they are expected to travel in the next few weeks.
A spokesman for the AMAR said: "We invited the three young Yazidi women to speak to school children in the UK because they were desperate to tell their horrific stories and stop other young people ever suffering the same experiences as them."
"When they met the girls from Bristol they were visibly shocked to hear that one of their classmates had voluntarily gone to join the extremists. They simply could not believe it.
"The Yazidis then detailed the horrific treatment they suffered at the hands of the thugs they call Daesh.
"These brave women were kidnapped, saw relatives shot dead in front of them, and were then held as sex slaves for months, and were raped virtually every day and horribly beaten.
"Some of the girls they were with committed suicide rather than continue with this torture."
