A woman reacts as she looks at a gruesome collection of images of dead bodies taken by a photographer, who has been identified by the code name "Caesar," at the United Nations Headquarters in New York, March 10, 2015. The pictures were smuggled out of Syria between 2011 and mid-2013. The exhibition at the UN consists of two dozen images selected from the roughly 55,000 photographs taken in Syria by a former military police photographer - some showing eye gougings, strangulation and long-term starvation - as the conflict in Syria enters its fifth year.
