While it is a start, the amount of humanitarian aid israel is allowing in is a tiny fraction of what is really needed. The red crescent will have to prioritise the hospitals at this time most likely.
I believe one of the analysts on al jazeera said that the border crossing will only be open for humanitarian aid for about 6 hours? And also that rafah border crossing can’t accommodate the big humanitarian aid trucks, so they have to use smaller trucks. So that also limits capacity of aid.
The big trucks usually go through the other border crossing that egypt shares with israel, but that one is closed. The name escapes me at the moment.
Edit: also, what the other commenter ssid is true; is it really going to happen this time? And will israel bomb this convoy of aid as well or will it be allowed to go to the palestinians in gaza?
