If you've been following the coverage of the recent Peshawar massacre, you'd have seen this photo. Everyone thinks it's a blood soaked child's shoe that was left behind after the incident, and it's all over Facebook and Twitter.

But the photo isn't from Peshawar. It's actually as old as the Israeli-Palestinian conflict. It was shot by photographer Edi Israel, while he was working as a freelancer in Ashkelon (Israel) in May 2008. After Israelis were hit by a rocket fired by Palestinian militants, the image represented the injury and horror of the incident.

Edi Israel told the BBC his feelings about the photo being used with reference to the Peshawar attacks, "I'm horrified to know that the picture has moved to Pakistan, and that it's being used like that. This is a known phenomenon that people take a photo from one place and use it like it was elsewhere."

The shoe was dropped by a mother and her daughter who were injured in the rocket attack. They survived, and Edi even visited them in the hospital. Interestingly, he didn't know the photo was floating around the web until the BBC got in touch with him.
