I don't mean protected in a military sense, I mean protected in a legal sense, ie, assuming your opponent is bound by international law, having them forbidden from attacking those places. In a more normal conflict, it's in the best interests of both governments to follow this sort of rule, since the military value of a hospital is (supposed to be) kept low, and each side knows that attacking medical facilities might lead to the other side doing the same in retaliation. However, this isn't really a normal conflict, and Hamas does not act like a state (since it isn't really, it's a terrorist group taking on some of the roles of a state).
