Israel has cut off outside provision, however as I said, Gaza has adequate fuel and food supplies to run their hospitals and other services, however they are being hoarded by Hamas for military purposes.
The humanitarian crisis is 100% Hamas' creation, unless you can suggest an alternative to Israel that doesn't involve doing nothing and then waiting for their people to be massacred in another cross border raid?
As for strikes to the south, you'll notice (if you care to) the vagueness of the reports. Israel are permitted to continue to hit military targets all over Gaza N and S while also providing designated safe areas in the S for temporarily displaced civilians to move to, which is exactly what they are doing.
It's Hamas who are stopping them and pushing false narratives that they will be 'targeted' in the South as well, as a way of cynically keeping civilians in their homes in the North in the hope it creates more casualties for them to exploit in the media.
I know who the real monsters are here.
