President Obama delivered an angry condemnation Wednesday of the Islamic militant group believed to be behind the beheading of an American journalist, labeling the group a cancer and calling on Muslims around the world to reject its brand of “hateful terrorism.” “No faith teaches people to massacre innocents,” Obama said. “No just god would stand for what they did.” The president said he had spoken with the family of the journalist, James Foley, and expressed his support. “Jim was taken in an act of violence that shocks the conscience of the entire world,” Obama said. “We are all heartbroken at their loss”/Los Angeles Times.
