ISIS says Jordan air strike killed American woman hostage

The Islamic State claims that the Jordanian air strikes over its bases in Syria Thursday night killed a 26-year old American female aid worker, hitting a building where was being held. In Washington, US officials said they could not confirm that the woman, who has been identified as Kayla Mueller, had been killed. Reuters also could not immediately confirm the report. Islamic State has murdered five British and American aid workers and journalists in recent months.
