US to question Islamic State leader's wife on hostages, officials say
The captured wife of a senior Islamic State leader who was killed in a weekend raid will face questions over what she and her husband knew about the group's treatment of hostages, including Americans, US officials said.
The US government believes the leader, Abu Sayyaf, was involved in handling foreign hostages, including Kayla Mueller, an American aid worker who was killed in February, US security and law enforcement officials said. The White House said on Saturday that US military personnel based in Iraq had carried out a raid in eastern Syria aimed at capturing Abu Sayyaf and his wife, known as Umm Sayyaf.
