No forensics are needed because the hospital was not hit by anyone. That is just a further lie.
There was footage the next day taken by a Gazan of the hospital showing it unscathed except for a small crater in the carpark. There were shattered windows in a nearby chapel. Unfortunately there were people camped in the carpark so about 20 people died (not 500 as Hamas lied).
Notice that Hamas didn't even release any footage of any damaged building let alone AlAhli hospital. They didn't even have to try because media around the world lapped it up without question.
There was also footage of the rocket barrage by the PIJ streamed live by Al Jazeera which showed one of the rockets boomeranging and a citizen's footage showing similar closer by.
I was outraged by the recent double tap of the hospital looking rescuers. Even if there was a Hamas base there it is inexcusable.
Apparently Hamas documents have been found last week showing their basing themselves in hospitals.
I can back up the above but I doubt people in this thread are interested in such messy departure from any narrative which isn't black and white.
