ISIS are using a charming ring to smuggle women and ladies into their country for sex slavery

ISIS terrorists have set up an international sex ring by smuggling kidnapped Yazidi women to foreign countries, rescued captives have revealed.

Dozens of women who were snatched from Yazidi villages across northern Iraq are said to have been taken to nations including Afghanistan, Pakistan, Libya and Chechnya, where they are being held as sex slaves.

The terror group abducted hundreds of women and young girls when it laid siege on the undefended towns in August 2014, killing thousands of men in the process.

'At this moment we do not know how these girls were moved outside of Iraq or Syria but we believe they could have smuggled them out of the countries overland,' said Mihemma Xelil the mayor of Shingal, one of the Yazidi villages attacked by ISIS.

Many of the women were moved to the nearby cities of Mosul and Tal Afar but they were soon taken to the groups strongholds, the Rudaw news agency quoted him as saying.

Survivors have told of how the 'most beautiful' women are sent to horrendous auction houses in ISIS's de facto capital of Raqqa, Syria, where they are stripped naked and sold to the highest bidder.

Xelil said: 'Many of the abducted women still have access to their cellphones and speak to their families and ask for ransoms to be paid for their release.'

Of around 6,000 people abducted by ISIS in Sinjar province, almost 4,000 are still thought to be imprisoned by the terror group, local government officials have claimed.

Ransoms have been paid for 'many' of the victims, according to Hussein Koro who manages the office on behalf of the Kurdistan Regional Government (KRG).

Koro told Rudaw: 'In many cases, when we could not verify a source and therefore decided not to pay the ransom, the relatives of the victim paid it themselves and many times it turned out to be false sources who were after the ransom money.'

Xudeda Misto, 75, from Shingal, has not seen his wife, three daughters or his son since they were abducted by ISIS thugs in 2014.

He said: 'They have asked for $15,000 for my eldest daughter who is now in Syria, but I have only $5000 and could not make the rest.'

Amnesty International has said hundreds - possibly thousands - have been forced to marry, been 'sold' or given as 'gifts' to ISIS fighters or their supporters - and many held as sexual slaves are girls younger than 14.

In May, ISIS released a chilling document in which it justified the kidnapping and rape of Yazidi girls it enslaved.

The shocking admissions were made by a jihadi bride in the ninth edition of Islamic State's propaganda magazine Dabiq in a feature entitled: 'Slave girls or prostitutes.' She describes the cruel sex crimes as Sunnah which roughly translates as 'a way of life'.
