I'm trying to stay off this thread, but I'm quite shocked at your complete (wilful?) ignorance here
Karl Masks.
Hamas and PIJ have been firing loads of rockets out of Gaza, there's videos of them doing it made
by themselves, plus all the tracking and other video footage. And it's not the only example of a rocket fired at Israeli going wrong, it's estimated around 30% fail to reach their target through malfunction. I can't be arsed to show you the info, but it's out there if you do the most cursory look.
You must have to put some effort in to stay this ignorant.
