President Barack Obama on Sunday confirmed that Peter Kassig, also known as Abdul-Rahman Kassig, was beheaded by ISIS.
Kassig “was taken from us in an act of pure evil by a terrorist group that the world rightly associates with inhumanity,” President Obama said in a statement.
Militants claimed to have beheaded Kassig in a video published to the Internet on Sunday, purportedly from terror group ISIS.
Kassig, 26, who converted to Islam in captivity, also went by the name Abdul-Rahman Kassig.
He went to the Middle East as a U.S. soldier and returned as a medical worker, feeling compelled to help victims of war.
He did aid work in Syria, where he was captured. He was held hostage for over a year.
Kassig’s parents, Ed and Paula Kassig, acknowledged the reports of their son’s death in a statement and said they would wait for government confirmation of their authenticity. They asked for privacy.
