Though unsubstantiated, the Islamic State (ISIS) claimed on Friday that a female U.S. hostage, named as Kayla Jean Mueller, was killed in during a bombing raid on Syrian targets by the Jordanian military.

As the Guardian reports:

Mueller, originally from Prescott, Arizona, was allegedly kidnapped by ISIS fighters in August 2013 after leaving a hospital run by the Spanish branch of Medecins San Frontieres in the Syrian city of Aleppo.

In the statement posted to social media, those appearing to speak on behalf ISIS said that nobody but Mueller was killed in the attack, stating, “The criminal crusader coalition planes targeted sites outside Raqqa city today at noon time while people were performing Friday prayers… The raids continued on the same site for more than an hour. God has disappointed their endeavours and foiled their plot by not hitting any jihadi man thank God.”
