US female hostage killed, says IS

The Islamic State group claimed on Friday that a female American hostage had been killed in an air strike in Syria by the US-led coalition.

In a statement posted on jihadist websites, IS said the woman was buried beneath the rubble after a raid by a Jordanian warplane in Raqa, the self-proclaimed capital of the militant group.

The statement did not show any pictures of a body and there was no independent confirmation of her reported death.
