I was just sharing what I remembered from reading the ICRC website and other sources a while back (probably last year or something).

Here is what I found on their website right now:

If armed forces are using a hospital or school as a base to launch attacks or store weapons, are those places then a legitimate military target?

The laws of war prohibit direct attacks on civilian objects, like schools. They also prohibit direct attacks against hospitals and medical staff, which are specially protected under IHL. That said, a hospital or school may become a legitimate military target if it contributes to specific military operations of the enemy and if its destruction offers a definite military advantage for the attacking side.

If there is any doubt, they cannot be attacked. Hospitals only lose their protection in certain circumstances - for example if a hospital is being used as a base from which to launch an attack, as a weapons depot, or to hide healthy soldiers/fighters. And there are certain conditions too.

Before a party to a conflict can respond to such acts by attacking, it has to give a warning, with a time limit, and the other party has to have ignored that warning. Some States have endorsed the Safe Schools Declaration and Guidelines, which aim to reduce the military use of schools.

I have read more about it earlier and I could probably give you some more quotes and links but right now I don’t care enough.

Also is Israel torturing patients and staff? That’s the first I’ve heard of it. Got any credible sources? If not, it’s a pretty wild accusation.
