Beheaded U.S. hostage remembered for fearless dedication to refugees

(Reuters) - Peter Kassig, the U.S. aid worker beheaded by Islamic State militants who captured him in Syria last year, was remembered on Sunday for his courageous devotion to helping people whose lives were upended by civil war.

The parents of the 26-year-old medic and former U.S. Army Ranger, who pleaded in a video message to his captors last month to spare their son's life, said they were heartbroken.
