The family of Kayla Mueller, an American hostage of the Islamic State, has received confirmation that she is dead.
Mueller, 26, was captured in August 2013 while working as a humanitarian aide in Aleppo, Syria. The Islamic State demanded a $7 million ransom with a deadline of Aug. 13, 2014, but what happened to Mueller after the deadline is unknown.
"We are heartbroken to share that we've received confirmation that Kayla Jean Mueller, has lost her life," said a statement released by Mueller's family.
The Islamic State claimed last Friday that Mueller was killed in a Jordanian airstrike in Syria.
President Barack Obama released a statement confirming Mueller's death.
