October 6, 2014 Islamic State Beheads 4th Western Hostage; U.S. Aid Worker Threatened ---------------------------------------------------------------------- The latest violence comes as video was posted online showing an Islamic State member beheading British aid worker Alan Henning. He is the fourth Western hostage to be beheaded by the group in just over a month. In the video, the Islamic State issues death threats against another captive, U.S. aid worker Peter Kassig. In a statement, Kassig's mother Paula appealed for his freedom. Paula Kassig: "Please know that we are all praying for you and your safe return. Most of all, know that we love you, and our hearts ache for you to be granted your freedom so we can hug you again and then set you free to continue the life you have chosen, the life of service to those in greatest need. We implore those who are holding you to show mercy and use their power to let you go." .
