Now read the update on the articles you've posted as reference Hint: "No it wasn't".
It was proven with evidences that the attack did really happen, and UNRWA people were present when the attack happens, and being the UN representer in the Middle East or Ban ki Moon the general secretary of the UN condemned the attacks after checking all the factual evidence.
Not like it was the first refuge to be shelled anyway.
Even if the shelling of the school was not staged (I personally do not think it was), it is still a fact that the terrorists are keeping bombs, and rockets inside schools and hospitals so Israel looks bad when they attack places housing these war items.
Hammas is very good at propaganda and making Israel look very bad, at least on paper. I have also read they have gotten citizens to go to their roofs when they receive texts saying their house is about to get bombed to try to get the IDF not to bomb the house. They are really doing nothing kore the using their citizens as human shields.
I'm mesmerized at people calling stuff propaganda when it was proven and judged it wasn't I can quote several resources being it UN, International press, or different ONGs that the hospital was hit by an artillery ammo and they have the fragments of it.
Here is a video presenting some of those quotes from TYT

Here are some soft proves and there are even horrible things that I will not post in respect to the people reading this and it is not like the first thing I've posted this

I think you are the one that been subject to Israeli propaganda and you are believing it at that .....where facts can be easily found all over the Internet and compare for your self which things makes sense in comparison to the consequence on ground
