A former school teacher who fled ISIS in Iraq has described how a metal torture device known as 'the Biter' causes pain 'worse than childbirth'.
The tool has been described as a device similar to a hunting trap - a metal clamping jaw with sharp teeth that cut into the flesh of the victim.
The brutal instrument, also known as 'the Clipper', is reportedly used to punish women in the ISIS-held city of Mosul, when they venture out with any skin on show.
The extremists insist that any woman in public should be fully veiled, wear loose or baggy trousers, socks, gloves and be accompanied by a male relative.
And now Fatima, who fled the terrorist stronghold told the Independent how her sister was punished with 'the Biter' because she had gone outside with her hands on show after forgetting her gloves.
The 22-year-old, who is now a housewife said: 'The Biter has become a nightmare for us. My sister was punished so harshly last month because she had forgotten her gloves and left them at home.
'The bruises and scars are still visible on her arm. She said the biting punishment is more painful than labour.'
Fatima said she decided to flee the brutal regime and head for a refugee camp in Kurdish-controlled Syria after seeing the terror group become more violent in the past year.
She also added that she decided to make the journey after several failed attempts as her children were starving.
It is not the first time that reports have suggest the jihadist group have used the torture device.
In 2014, a woman in Raqqa spoke out saying her chest was clamped by the spike after she tried to breastfeed her baby.
She said: 'did not know what a "biter" was and I thought it is a reduced sentence, I was afraid of whipping, so I choose the "biter", then they brought a sharp object that has a a lot of teeth and held me, placing it on my chest and pressing it strongly, I screamed from pain and I was badly injured. They later took me to the hospital.
'I felt then that my femininity has been destroyed completely, we can no longer afford to live this way, I was not the only one that was tortured with this instrument, there were a lot of women in the headquarters and their situation was tragic.'
Meanwhile many people who have fled the regime and made it to the refugee camp confirm that Mosul is running short of food, water, fuel and electricity.
Baby milk has not been available for six months and a kilo of rice costs more than £7.
In addition, public executions and whippings are said to be becoming ever more frequent as ISIS loses ground in an attempt to set up a self-styled caliphate.
It has imposed its own sickening brand of medieval justice across swathes of territory in Iraq and Syria, executing prisoners for so-called 'crimes' such as blasphemy and being homosexual.
In a statement two years ago, the terror group also banned 'music and songs in cars, at parties, in shops and in public, as well as photographs of people in shop windows.'
