This photo of a Syrian child so scarred by war that she stared into a camera lens believing it was the barrel of a gun and raised her arms in surrender has been shared around the world.The fear in the little girl’s eyes as she bit her lip to stop herself crying has caused an outpouring of emotion about the “heart-breaking” image showing how “humanity failed” in the Syrian civil war.It spread across social media this week after it was tweeted by a photojournalist in Gaza.Nadia Abu Shaban’s post on 24 March has been shared more than 14,000 times, sparking threads on Reddit and other forums being inundated with thousands of comments. She said the child thought the photographer had “a weapon not a camera” but the lack of further information caused viewers to speculate that the image was fake, posed or taken in an unrelated situation.
