A depraved Islamic State militant used an 11-year-old sex slave as a human shield by strapping her to the bonnet of his car while driving into battle.

The terrified girl was left screaming for her life after being tied to the windscreen of a Humvee military vehicle to protect her captor from enemy gunfire.

When she is not being paraded through war zones, the Yazidi child is repeatedly raped by the fanatic, activists have revealed.

The girl is among 3,750 prisoners from the minority sect who were captured during the terror group's brutal uprising through northern Iraq last year.

Sickening: A depraved Islamic State militant used an 11-year-old sex slave as a human shield by strapping her to the bonnet of a military Humvee (like the one above) while driving into battle

Many have been sold at slave markets destined for a life of sickening abuse at the hands of their captors.

Lawyer Khaleel al-Dakhi, who runs a group that has rescued more than 1,000 Yazidis from ISIS through a network of informers, said the girl was still being held by her captor.

He told The Sun: 'He rapes her. She told me herself over the phone.'

Baroness Emma Nicholson of Winterbourne, who sits in the House of Lords, has compared the treatment of the Yazidis by ISIS to the Holocaust.

Speaking on a visit to a refugee camp in Iraq to highlight their ordeal, the 73-year-old said: 'The stories are mirror images of the foulest stories from Belsen and Auschwitz concentration camps.

'It's a re-run of the stories I heard growing up as a post World War Two child. This is Hitler and Stalin all wrapped up together.'

One victim, a mother-of-three named Khalida who managed to escape, told how the disabled and elderly women were separated for prisoner swaps and that virgins were also singled out.

And their fate can also be death for those who disobey.

ISIS'S DESPICABLE 'PRICE LIST' FOR YAZIDI AND CHRISTIAN SLAVES A translated version of the document (left) was shared online by humanitarian and peace prize winner Dr Widad Akrawi, and reads as follows: We have received news that the demand in Women and Cattle market has sharply decreased and that will affect Islamic State revenues as well as the funding of mujahideen in the battlefield, therefore we have made some changes. Below are the prices for Yazidi and Christian women. The price for Yazidi or Christian women between the age of 40 - 50 is $43 (£27) $75 (48) for 30 to 40-year-olds $86 (£55) for 20 to 30-year-olds $130 (£83) for ten to 20-year-olds $172 (£110) for one to nine-year-olds Customers are allowed to purchase only three items with the exception of customers from Turkey, Syria and Gulf countries.

Just last week it emerged that ISIS fanatics had executed 19 women for refusing to have sex with its fighters.

A Kurdish official claimed the women were being held hostage in Islamic State's stronghold of Mosul, Iraq, which the terror group seized in June last year.

Meanwhile a UN envoy investigating Islamic State's vile sex trade has said 'girls get peddled like barrels of petrol' and one can be bought by six different men.

She also verified a disturbing ISIS document which suggested the extremists sell the Yazidi and Christian women and children they have abducted, with girls aged just one to nine-years-old fetching the most money.
