Wife of Islamic State leader charged in death of American: U.S. Justice Dept.

WASHINGTON (Reuters) - The wife of a deceased Islamic State leader was charged on Monday with conspiracy in the death of an American aid worker who was killed a year ago while being held hostage in Syria by the militant group, the U.S. Justice Department said. Nisreen Assad Ibrahim Bahar, 25, an Iraqi citizen and wife of Abu Sayyaf, a senior Islamic State leader until his death last year, was charged for her role in a conspiracy that resulted in the death of Kayla Mueller in February 2015, the Justice Department said in a statement.
