British women are suspected of running sex slave brothels for Islamic State fighters in Syria.
They are among scores of European women who have flocked to the warzone in the hope of becoming ‘jihadi brides’.
Academic experts monitoring the lawless region have identified at least 11 women linked to frontline fighters.
One British woman, Umm Farriss, wrote recently on social media complaining that a sex slave had dared to look her in the eye.
A teenager posted a picture of Adolf Hitler with the words, ‘I could have extinguished every Jew in Europe but I left them so you would be able to do it for me.’
Another commented ‘I wish I did it’ after being asked about the murder of Israeli-American journalist Steven Sotloff.
