The news broke today that ISIS is claiming that the American hostage whose name was accidentally leaked by White House Chief of Staff Denis McDonough, Kayla Mueller (whose family has now publicly identified her), was killed in Jordanian airstrikes on ISIS locations.

From ABC News:

The terror group ISIS released a statement today claiming that Kayla Mueller, a female American hostage the group had been holding, was killed in a Jordanian airstrike recently. The statement, which circulated on Twitter, said an airstrike outside Raqqa, Syria killed the 26-year-old Mueller. The statement used Mueller’s full name, which had not been public. The claim could not be immediately confirmed and ISIS did not provide photographic evidence of Mueller’s death, as the group has in the past with other hostages and its own fighters.

Fox News released a comment from the Jordanian government, saying that they don’t really believe ISIS, given how the negotiations for their own pilot turned out.

Here’s a statement from the Jordanian government: The first reaction we think that it’s illogical and we are highly skeptical of the ISIS claim. How could they identify Jordanian war planes at such a huge distance in the sky? What was the American lady doing in the weapon warehouse? It’s part of their criminal propaganda. They have lied that our pilot is alive, and tried to negotiate claiming that he was alive while they killed him weeks before.

Fox News chief intelligence correspondent Catherine Herridge said this hour that U.S. intelligence officials are investigating the credibility of the claim. ISIS claimed that Mueller was killed in an airstrike on a weapons depot, releasing a photo of a bombed-out building.

Mueller had gone to Syria to work with the humanitarian aid group Support to Life, and was kidnapped by ISIS in August 2013. Mueller was the last known American hostage in ISIS custody.
