Abu Anas Al-Libi executed the women before burying their bodies in mass graves in Fallujah in the Iraqi province of Al Anbar, the Iraqi Ministry of Human Rights said in a statement. It is thought he killed the women, most of whom were Yazidi, because they refused to enter into sham temporary marriages with Islamic State fighters, where they would effectively be treated as sex slaves. 'At least 150 females, including pregnant women, were executed in Fallujah by a militant named Abu Anas Al-Libi after they refused to accept jihad marriage,' the statement said. 'Many families were also forced to migrate from the province's northern town of Al-Wafa after hundreds of residents received death threats.' The statement went on to say that the militants then turned a mosque in Fallujah into a prison, where they held hundreds of men and women. Al- Libi is not the extremist with the same name who is alleged to have helped carry out East Africa's embassy bombings in 1998 that killed 224 people in Kenya and Tanzania. ISIS fighters have taken thousands of women and children as captives, especially around 2,500 women from the minority Yazidi sect in Iraq.
