Israel during this action in Gaza has opened and publicized protected corridors for Gaza civilians to flee from Hamas and be protected in Israel run refugee camps.
Israel isproviding food etc for those in refugee camps (in tents).
Hamas-controlled areas had been getting UNRA food and supplies, handed to Hamas who then “sold” it to trapped civilians at extortion prices... or required the men to “join” Hamas in order to get food for their families.
It is the latter supplies which are being halted. Civilians can flee to Isarael=controlled camps to get food/supplies.
Forgive me but I’ve not heard this just they have blockaded since March
Read the link I posted
The food charities are pulling out
We’re days away from potential catastrophe
Those that don't leave are supporters of Hamas.
