Both sides are trying to do an ethnic cleansing. False flag operations don't make a lot of sense when your people are 'the chosen ones'.

I personally thought it was Israel because it sounded very much like a US JDAM but surprise surprise, the damage and death toll was extremely exaggerated by outlets which makes me think it actually was a faulty Hamas rocket on the basis it only cooked a few cars and scorched some stuff. The damage is too small to be Israel which is depressing in its own way.
