ISIS demand U.S government pay $6.6million ransom for 26-year-old American woman held hostage

 A 26-year-old aid worker who was kidnapped from Syria last year has been confirmed as the third hostage held captive by the Islamic State (aka ISIS).

The terror-group has demanded a $6.6million ransom for the woman, as well as the release of imprisoned neuroscientist Aafia Siddiqui, ABC News reports. 

The hostage's family has asked for her name not to be released for fear of her safety.  She is the third of at least four hostages held by ISIS, including executed photojournalist James Foley.
