It will be shocking if this image, tweeted by Israeli BDS campaigner (Boycott, Divestment and Sanctions Against Israel) Ronnie Barkan and picked up by Israel-Gaza news site Mondoweiss, is the genuine article.
The photograph depicts a mortar shell with the words 'That's for cancelling the Backstreet Boys, you scum!' inscribed on its shaft in Hebrew.
The author, who appears to be a member of the IDF and a strident Backstreet fan, would have been referring to the recent rescheduling of the boyband's first ever string of dates in Tel Aviv, which were set to start 30 August.
The American pop group were forced to cancel for safety reasons, as the tensions between Israel and Gaza grew and the Israeli government launched an aggressive offensive against the strip.
The source of the photograph appears to be a pro-Israel Defence Forces Facebook page, called 'Standing By IDF', which has notched up over 30,500 likes since it was founded on 23 July.
