Finger Pointing For Al-Ahli Hospital Massacre

A missile lands on the Al-Ahli Hospital in Gaza and immediately Israel says they didn't do it, it was them as they would and then Hamas say they didn't do it, it was them as you would also expect them to do.
Obviously Israel and Hamas have a long history of flat out lying so you would be an idiot to take either of them at their word so we will have to wait for an independent assessment before we apportion any blame but almost 500 people died so someone has to be held to account and although Britain's backing of Israel's
ongoing slaughter in Palestine is abhorrent, Rishi got it right to not follow America's lead and immediately accept Israel at face value and blame one of the Palestinian groups.
We have already discovered that their 'evidence' included a discussion between Islamic Jihad members discussing the missile which dropped short and landed on the Hospital turned out to be fake and the Israeli Government first said they targeted rockets being launched from the Hospital roof before changing their story so not a trustworthy source to be making such a big call from.
We do know that Islamic Jihad WERE firing rockets into Israel at that time and we also know that Israel WERE firing missiles into Palestine also at that time, Israel jets had hit the same hospital days before and just prior to the Hospital being hit it had destroyed a UN run school so both were actively in a position to have hit the Hospital.
Based on footage available of the scene, experts are split between a rocket failure and an airstrike but they are all heavily emphasizing that it is not by any means conclusive as given the size of the explosion it could only be an Israeli air strike but they are also saying the crater is too shallow so that could only be made by a rocket failing. 
We can imagine that whoever is to blame, many people have already made up their minds.
