White House says authenticating Jordanian hostage video

The White House said on Tuesday the U.S. intelligence community was working to authenticate a video purporting to show Islamic State burning a Jordanian pilot hostage alive, and it condemned the militant group. "The United States strongly condemns ISIL’s actions and we call for the immediate release of all those held captive by ISIL," White House spokeswoman Bernadette Meehan said in a statement, using another acronym for Islamic State.
