British female jihadis are running brothels full of women kidnapped and forced into sex slavery by Islamic State militants.

Members of the all-women al-Khanssaa Brigade in Raqqa, Syria, are running brothels for Islamic State murderers

It is understood they are members of an ultra-religious IS ‘police’ force tasked with looking after girls captured from the Yazidi tribe in Iraq.

As many as 3,000 Iraqi women have been taken captive in the last two weeks by the terror group.

Sources suggest that members of the all-women al-Khanssaa Brigade in Raqqa, Syria, are running brothels to satisfy the fighters’ desires.

One said: “These women are using barbaric interpretations of the Islamic faith to justify their actions.

“They believe the militants can use these women as they please as they are non-Muslims.

“The Yazidi people are being ethnically cleansed, and their women are being subjected to the most brutal treatment.

“It is the British women who have risen to the top of the Islamic State’s sharia police and now they are in charge of this operation.

"It is as bizarre as it is perverse.”

A report obtained by the Daily Mirror from researchers at think tank MEMRI – the Middle East Media Research Institution – confirms ethnic sex slavery is taking place on a massive scale.

The report states: “During its takeover of large parts of northern Iraq the IS captured many Yazidi villages, and reportedly took many Yazidi women to be sold and used as sex slaves.”

Researchers at the International Centre for the Study of Radicalisation suggest up to 60 British women have gone to Syria for jihad.

Sources have revealed some of these women have emerged as key figures in the al-Khanssaa brigade and are enticing dozens more to leave their families and join them.

Aspiring doctor Aqsa Mahmood, 20, who fled her Glasgow home last November, is understood to be part of the brigade.

She said she wanted to behead Christians with a “blunt knife”.
