Parents of US hostage appeal to ISIS captors
None
The parents of a US hostage who ISIS jihadis claimed had been killed in an airstrike said on Friday they were "hopeful" she was still alive and appealed to her captors to contact them.
The militants said Kayla Jean Mueller had been buried under rubble after a raid by a Jordanian warplane in the Syrian city of Raqqa, the extremists' self-proclaimed "capital."
