Showed scars caused by being shot three times during firefight with Kurdish troops who subsequently took him captive

Also described witnessing woman being brutally killed for showing her arms

A 15-year-old prisoner accused of having fought for ISIS has described how the terrorists murder women who show their skin and drug young men to convince them to carry out suicide attacks.

A group of accused men are being held in northern Syria after being captured earlier this year by Kurdish troops battling to force the jihadists out of the area.

While many of the prisoners deny being involved, teenager Kareem Mufleh readily admits his links to ISIS - claiming he had been threatened with beheading if they did not join the terror group.

Mufleh was eventually captured by Kurdish fighters in June, during a firefight in which he was shot three times in the stomach, leaving massive scars.

Experience: In order to ensure their largely reluctant recruits give their all in battle, ISIS makes them take the anti-anxiety drug Zolam to make militants willing suicide bombers, 15-year-old Kareem Mufleh claimed

Claims: Accused fighter Kareem Mufleh (standing) described how Islamic State terrorists murder women who show their skin and are known to drug young men in order to convince them to carry out suicide bomb attacks

The men accused of being Islamic State fighters were interviewed in the basement of their prison in northern Syria by Holly Williams, a correspondent for CBS News.

Among those interviewed was 15-year-old Kareem Mufleh, who openly tells of having fought for ISIS - something none of the other men in the jail admit to. His face was covered throughout the interview, presumably so ISIS fighters wouldn't recognise him.

But rather than joining the group voluntarily, Mufleh says the militants entered his village and gave all the men there the option of joining their campaign of terror or face being beheaded.

In order to ensure their largely reluctant recruits give their all in battle, ISIS makes them take the anti-anxiety drug Zolam to make the fighters' willing suicide bombers, Mufleh claimed.

'That drug makes you lose your mind... If they give you a suicide belt and tell you to blow yourself up, you'll do it,' he said.

Injury: 15-year-old Kareem Mufleh revealed three large wounds on his stomach which he claims were received while fighting the Kurdish troops who would eventually take him captive

Describing the horrors of his time in ISIS' ranks, Mufleh says: 'I even saw them kill a woman because her wedding dress showed her neck and bare arms.'

He also revealed three large wounds on his stomach which he claims were received while fighting the Kurdish troops who would eventually take him captive.

Mufleh's story is a long way from the myth ISIS likes to propagate, that its followers are pious men and women drawn to the group's hardline interpretation of Islam.

The reality in many cases is that ISIS' reputation for bloody violence is the only thing encouraging new recruits from within the many towns and villages the terror group has seized in recent months.

This morning a terror expert described how ISIS grooms Western fighters in much the same way as paedophiles do with children.

Professor Greg Barton, from Australia's Monash University's Global Terrorism Research Centre, told AAP that recruiters lure targets by making friends through social media, like many sexual predators.

'Somebody might strike up a friendship in an online chat forum and present themselves in a different fashion - to try to get them into their web... By the time they actually meet the people they're speaking with, they may be in too deep to know better.'

While that approach may work with naive Western recruits, the reality is that for many of those already living under ISIS' bloody oppression, it is only the fear that the group's leadership will murder either them or their loved ones, that encourages militants to take up arms for the Islamic State.
