re: smuggling siege equipment (oxygen concentrators should be amongst the medical aid) amongst humanitarian aid food...
https://youtu.be/W4gDfSNMRx4?si=3NhT_Xt2Dxxkp3A- at around 6 minutes you can see Hamas using concentrated oxygen in the tunnels to refresh themselves. Lot of morons with "underground mine experience" who also don't know its a standard practice outside of Gaza. https://www.amsj.com.au/dont-hold-breath/

Israel doesn't operate the Egypt side and Egypt wants to not be an active participant beyond maintaining the crossing. They especially don't want to run a PoW camp.
Working with the IDF directly to transfer prisoners to them would probably start shit in Egypt Sisi doesn't want to start as it would be seen as entering the war I guess. Iran backed Houthi rebels in Yemen are already doing War Crimes on Egyptian hospitals for their current stance.
