Doctor's photo of Paris attack goes viral

Dr. Pourya Pashootan saved countless lives in the emergency room on Friday night in the wake of the Paris terror attack. He recounts the "war scene" he saw and "the fear in the eyes" of his patients. But in the midst of the horror he took a photo that embodies hope: a scene of all the doctors at work in the ER. The photo had gone viral -- and in his only on-camera interview, he spoke with CNN about the message he hoped to send the world with his picture: "We are together" -- always.
