US intelligence officials are investigating a claim by the IS group that its sole known remaining American hostage, an aid worker held for nearly a year and a half, has been killed.
Kayla Mueller, 26, whose identity had previously not been revealed at the request of the US government and her family as the Pentagon worked to secure her, is believed to be the last American hostage the terrorist army is holding, since the beheading of Peter Kassig, a 26-year-old American aid worker, killed in November.
In its statement, the terrorist group claimed Mueller was killed by an airstrike, adding that none of its fighters were injured or killed.
US National Security Council spokeswoman Bernadette Meehan said: "We are obviously deeply concerned by these reports. We have not at this time seen any evidence that corroborates ISIL’s claim."
