Iraqi woman charged with role in Kayla Mueller's death

WASHINGTON -- The wife of a senior Islamic State leader who was killed in a U.S. raid last year has been charged in federal court with holding American Kayla Mueller hostage and with contributing to the aid worker's death, the Justice Department said Monday.

Nisreen Assad Ibrahim Bahar, also known as Umm Sayyaf, admitted after her capture in May she and her husband kept Mueller captive with several other young female hostages, according to an FBI affidavit filed in the case. U.S. officials have said while in custody, Mueller repeatedly was forced to have sex with Abu Bakr al-Baghdadi, leader of the Islamic State group.

The criminal complaint, filed in federal court in Virginia, charges Umm Sayyaf with conspiracy to provide material support to a foreign terror organization, resulting in death.

The case comes one year after Mueller was confirmed dead by her family and the Obama administration, though it's not clear when or whether Umm Sayyaf will be brought to the U.S. to stand trial.

The 25-year-old Iraqi woman, who was captured last year, is in Iraqi custody and facing prosecution there. Her husband, Abu Sayyaf, a former Islamic State minister for oil and gas, was killed in May in a Delta Force raid of his compound.

"We fully support the Iraqi prosecution of Sayyaf and will continue to work with the authorities there to pursue our shared goal of holding Sayyaf accountable for her crimes," assistant attorney general John Carlin, head of the Justice Department's national security division, said in a statement. "At the same time, these charges reflect that the U.S. justice system remains a powerful tool to bring to bear against those who harm our citizens abroad. We will continue to pursue justice for Kayla and for all American victims of terrorism."

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. Mueller had begged him to let her tag along because she wanted to do relief work in the war-ravaged country. Alkhani was released after two months, having been beaten.

According to the FBI affidavit, Mueller was transferred in September 2014 along with several other female captives from an Islamic State prison to the Sayyafs. The couple at times handcuffed the captives, kept them in locked rooms, dictated orders about their activities and movements and showed them violent Islamic State propaganda videos.

After her capture last year, according to the affidavit, Umm Sayyaf admitted she was responsible for Mueller's captivity while her husband traveled for Islamic State business.

The Justice Department's case echoes earlier assertions from U.S. intelligence officials, who had told Mueller's family that their daughter was repeatedly forced to have sex with al-Baghdadi.

According to the affidavit, Umm Sayyaf said that al-Baghadi would occasionally stay at her home and that he "owned" Mueller during those visits, which the FBI says was akin to slavery.

A Yazidi teenager who was held with Mueller and escaped in October 2014 said al-Baghdadi took Mueller as a "wife," repeatedly raping her when he visited. The 14-year-old Yazidi girl made her way to Iraqi Kurdistan, where she talked to U.S. commandos in November 2014. Intelligence agencies corroborated her account and American officials passed it on to Mueller's parents in June 2015.
