USA: Peter Kassig was killed while helping Syrian refugees

Parents of the beheaded American aid worker, Peter Kassig reacted to the news of their son’s murder by the barbaric ISIS group. They expressed sorrow and pain for the loss of their 26-year-old son and wrote in their tweeter “He died for his ideals in helping the needy Syrian people.”
They had repeatedly asked ISIS to release their son and not to execute him.
Peter Kassig was the fifth Western citizen who dies in captivity in the hands of ISIS or as they are known in Middle East “DAESH”. US president Barack Obama called it a “heinous” and “evil” crime.
