Obama confirms death of American aid worker Kayla Mueller
The American aid worker, 27-year old Kayla Mueller, held hostage by ISIS since August 2013, has been killed. President Barack Obama has just confirmed that there is proof of the Islamist State’s claim of her death. : A spokesperson for the White House National Security Council said that over the weekend, the Mueller family "received a private message from Kayla's [ISIS] captors containing additional information." "Once this information was authenticated by the intelligence community, they concluded that Kayla was deceased," NSC spokesperson Bernadette Meehan said.
