Just In-- ISIS Beheads Second American Journalist (Photo)

 ISIS claims in a new video released Tuesday to have executed by beheading Steven Sotloff, the American journalist who was shown in last month's video execution of James Foley. The executioner was apparently the same in both videos.
 In the video, ISIS threatened Sotloff would be killed unless the U.S. stopped air strikes in Iraq. Last week, the 31-year-old freelancer's mother released a video plea to the group to spare her son. “As a
mother, I ask your justice to be merciful and not punish my son for matters he has no control over,” she said.
