Iraqi woman charged with role in Kayla Mueller's death

The wife of a former senior leader of the Islamic State has been charged in federal court with contributing to the death of American hostage Kayla Mueller.

The Justice Department on Monday announced charges against 25-year-old Nisreen Assad Ibrahim Bahar, who's also known as Umm Sayyaf.

A criminal complaint accuses Sayyaf and her husband, Abu Sayyaf, of holding Mueller and other women captive. U.S. intelligence officials have told Mueller's family that their daughter was forced to have sex with Abu Bakr al-Baghdadi, the leader of the group.

Abu Sayyaf was killed in a Delta Force raid of his Syrian compound in June, and his wife was turned over to Iraqi authorities for prosecution.

Justice Department officials say they support that prosecution, but they'll continue to "pursue justice for Kayla."
