I think the PP meant Gazan doctors not international ones, who are careful never to say they witnessed any injuries taking place and also to never mention Hamas.
Of course Palestinians are going to say Israel attacked them but it could just as well be a Hamas drone or sniper, rocket, IED, land mine or not evacuating either by force or choice.
Some doctors in Gaza have been linked to Hamas which makes logical sense as we know Hamas use hospitals as bases and munitions stores, and also kept hostages in hospitals. Including the young female hostage that was left to die by a Gazan doctor. They also use ambulances to get around Gaza. Doctors will know this is going on so it makes sense that there are doctors who are part of Hamas.
