Murdered ISIS hostage Kay Mueller ‘was raped repeatedly by militant group’s

The family of Kayla Mueller said in an interview Friday that FBI had informed them that the emir of the self-proclaimed Islamic State, Abu Bakr al-Baghdadi, had sexually abused their daughter, a humanitarian worker.

The fresh revelations about Mueller’s ordeal shatter rumours that she cooperated or was a willing spouse, which had deeply upset her family, ABC said.

Mueller, from Prescott, Arizona, was taken hostage with her boyfriend, Omar Alkhani, in August 2013 after leaving a Doctors Without Borders hospital in Aleppo, Syria, where he had been hired to fix the Internet service for the hospital.

The Muellers have been told she can be expected to serve a long prison sentence, Lenzner said.

“They told us that he married her, and we all understand what that means”, Carl Mueller, Kayla’s father, told The Associated Press on Friday, which would have been his daughter’s 27th birthday.

Abu Bakr al-Baghdadi repeatedly raped and tortured the 26-year-old Arizona woman while she was being held captive in Syria, counterterrorism officials told ABC News.

Officials stressed that all of what transpired with many girls kept as sex slaves in the Sayyaf household hasn’t been reconstructed completely and is still is in the process of being verified, though al-Baghdadi’s role in abusing Mueller is certain.

According to the escaped girls, Kayla was held in the home of Abu Sayyah, a Tunisian man in charge of ISIS’ oil and gas revenue. McCain questioned the reasons for her evading US justice. “And we are in very close contact with the family trying to keep them updated”. How Kayla Mueller actually died isn’t known, officials told ABC News.

A report released in April by Human Rights Watch accused the Islamic State of war crimes in its brutal treatment of female members of the Yazidi religious sect – many of them teenagers – who were captured in Iraq last August, taken to Syria and forced into sexual slavery by the Islamic State.

From that point forward, the military’s Joint Special Operations Command zeroed in on Abu Sayyaf.

It was initially suspected by U.S. officials that Mueller had been forced into a “marriage” to Sayyaf. Umm Sayyaf has been turned over to the Iraqi Kurds for trial.

It turns out it was the leader who imprisoned the young woman.
