Over the past week the hashtag #GazaUnderAttack has been used hundreds of thousands of times, often to distribute pictures claiming to show the effects the airstrikes.  Some of the images are of the current situation in Gaza, but a #BBCtrending analysis has found that some date as far back as 2009 and others are from conflicts in Syria and Iraq.

Mainstream American Jewish organizations reacted with grief and fury to the murders of kidnapped Israeli teenagers Naftali Fraenkel, Gilad Shaar and Eyal Yifrach, while their liberal counterparts responded with grief and calls for peace.

It's a truth of warfare in the digital era: Bullets and bombs often are augmented by status updates and tweets.  The bloody conflict taking place in Iraq is no different.
