"I was using a telephoto lens, and she thought it was a weapon," says Sağırlı. "İ realised she was terrified after I took it, and looked at the picture, because she bit her lips and raised her hands. Normally kids run away, hide their faces or smile when they see a camera."

The caption on the photo reveals just a small amount of the horror that a child whose natural reaction to a camera is so unnatural would have already experienced: ‘His face suddenly drops. He squeezes his bottom lip between his teeth and gently lifts up his hands. Where he remains like that without a word. It is not exactly easy to cheer up the child who thought the camera was a machine gun about to strike him. Adi Hudea, only four years old, lost his father in the Hama bombing. He went to Camp Atmen on the border of Syria/Turkey with his very nervous mother and three siblings.’

BBC Trending spoke to Sağırlı - now working in Tanzania - to confirm the origins of the picture. The child is in fact not a boy, but a four-year-old girl, Hudea. The image was taken at the Atmeh refugee camp in Syria, in December last year. She travelled to the camp - near the Turkish border - with her mother and two siblings. It is some 150 km from their home in Hama.
