ISIS Claims Jordanian Airstrike Killed 26 Year Old U.S. Hostage Kayla Mueller

ISIS is claiming that 26 year old US hostage Kayla Mueller was killed Friday during when a Jordan fighter plane bombed the building where she was being held near Raqqa. However, it could not be confirmed and the Islamic State has provided no proof of their allegations. Kayla Mueller was kidnapped in August 2013 when she was leaving a hospital run by Spanish Doctors Without Borders in the Syrian city of Aleppo.

The Islamic State claimed that a 26-year-old Arizona woman taken hostage by the group in Syria was killed Friday when a Jordanian fighter plane bombed a building where she was being held.

The claim could not be immediately verified, nor was it clear that Jordanian planes had bombed that location, described as being near Raqqa, the group’s de facto capital. The group released photos showing rubble of a building it claimed had been struck in airstrikes, but no images of the hostage, Kayla Mueller.

“The criminal Crusader coalition aircraft bombarded a site outside the city of ar-Raqqah today at noon while the people were performing the Friday prayer,” the Islamic State said in a statement, according to SITE Intelligence Group, which tracks online postings by Islamist militant groups. “The air assaults were continuous on the same location for more than an hour.”

The statement included Mueller’s phone numbers and other personal information.

The White House has “not at this time seen any evidence that corroborates” the claim.

The White House has “not at this time seen any evidence that corroborates” the claim, said Bernadette Meehan, the spokeswoman for President Barack Obama’s National Security Council. The statement included photos allegedly of the bombed site but no images of Mueller.

We are obviously deeply concerned by these reports,” Meehan said.

Jordan has been launching increased airstrikes against ISIS in response to a video released this week that shows a captive Jordanian pilot being burned to death in a cage.

CBS News national security correspondent David Martin reports that a U.S. military officer said the building that ISIS claims the U.S. hostage was in “was a weapons storage facility, not anything that was assessed to be a hostage holding area.”

“We would not strike a facility that was a known or possible hostage facility,” the officer said.

UPDATE II: Family of U.S. Hostage of Islamic State Says Hopeful She is Still Alive.

The parents of an American humanitarian worker held hostage by Islamic State since August 2013 said on Friday they are hopeful she is still alive, after the group said she was killed in a bombing by Jordanian fighter jets.

Carl and Marsha Mueller, the parents of Kayla Jean Mueller, asked the Islamic State group to contact them privately, according to a statement released by a family representative.

In a message directed to “those in positions of responsibility for holding Kayla,” they said: “You told us that you treated Kayla as your guest, as your guest her safety and well-being remains your responsibility.”
