Does that mean Hamas did it? I don't know, again, you need evidence to point finger, if it was Israeli air/ground strike, you will be able to show remanent of the bomb or missile like casing, guidance system or even warhead. if it was Hamas own rocket, you can most likely find wire or circuit on the scene, no one can be sure until people actually walk the scene and collect those evidence and show us, what I am able to tell you is what missing from the scene, so I can tell you what it most likely wasn't
