American ISIS hostage Kayla Mueller has been confirmed dead, the 26-year-old's family said in a statement on Tuesday.

"We are heartbroken to share that we've received confirmation that Kayla Jean Mueller, has lost her life," Mueller's parents said in a statement released four days after the militant group claimed the Arizona native had been killed by a coalition airstrike near Raqqa, Syria.

"Kayla was a compassionate and devoted humanitarian. She dedicated the whole of her young life to helping those in need of freedom, justice, and peace," the statement added.
