ISLAMIC State militants have reportedly executed 250 women after they refused to take part in sexual jihad.

Reports have emerged that the girls were killed in the IS stronghold of Mosul after they refused temporary marriages to fighters and become sex slaves.

The girls were murdered, some alongside their families, following their refusal to abide by the militants’ demands in Iraq’s second largest city, The Hindu reported.

Kurdish Democratic Party spokesman Said Mamuzini told London-based Kurdish news agency AhlulBayt that girls were ordered to accept the temporary marriages or face certain death.

“At least 250 girls have so far been executed by the IS for refusing to accept the practice of sexual jihad, and sometimes the families of the girls were also executed for rejecting to submit to IS’s request,” he said.

An official from the Patriotic Union of Kurdistan (PUK) party Ghayas Surchi said women and human rights are continually being violated in IS-held territories.

Not only are women not allowed to go out alone but they cannot choose their partners.

Stories of IS brutality, particularly towards women, are not uncommon.

Last November, the world was horrified when the United Nations testimony revealed how a woman was burnt alive by Islamic State for refusing an extreme sex act.

Zainab Bangura, the UN’s special representative on sexual violence in conflict, said IS militants were institutionalising sexual violence, revealing how the brutalisation of women and girls is central to their ideology.”

She told of how “pretty virgins” were captured by jihadists to be used as sex slaves and were often sold several times, while young boys and men were killed.

In one case, a 20-year-old girl was burned alive because she refused to perform an extreme sex act.

And in March this year, German doctor Jan Ilhan Kizilhan revealed more harrowing details of how women and young girls are treated under Islamic State.

He said one young girl set herself on fire to make herself less attractive to her jihadist captors, while another eight-year-old was repeatedly sold and raped.
