A former Islamic State (IS) militant has revealed that young Muslim women travelling to Syria to marry jihadists are being passed between men at the rate of one husband a week.

While describing the shocking conditions in which young women lived in war-torn Syria, a 33-year-old former IS fighter named Hamza said that the girls were forced to marry and sleep with older commanders in marriages that lasted for just seven days, before being divorced and partnered with a new husband, reported The Daily Express.

The revelation has raised concerns over the fate of three British schoolgirls who are believed to have travelled to Syria to link-up with the extremists. Shamima Begum, Amira Abase, both 15, and Kadiza Sultana, 16, flew first to Turkey from U K before travelling by land to the Syrian border.
