The war veteran Jake Wood, head of Gaza Humanitarian Foundation (GHF), says in a statement on Sunday night that "it is not possible to implement this plan and simultaneously follow the humanitarian principles regarding humanity, neutrality, impartiality, and independence."
He urges Israel to expand emergency aid "through all mechanisms" and explore "innovative new methods" in order to deliver aid.
Harsh criticism
According to the plan, emergency aid through GHF would have been distributed via four distribution centers, three in southern Gaza and one in the central parts of the area.
Security would have been handled by a private American security company.
No traditional aid organizations are part of the plan, and the criticism has been sharp, for example, the UN's aid chief Tom Fletcher called the setup "a deliberate distraction."
It is unclear whether the plan that GHF was set to implement will happen at all.
Total blockade
On March 2, Israel initiated a total blockade against Gaza and its population of around two million people. Only last week, a smaller number of trucks with emergency aid began to roll into the area, a decision the Israeli leadership made for "diplomatic reasons," according to Prime Minister.
The measure has been met with harsh criticism from the international community – the UN's Food Programme (WFP) called it in a statement "a drop in the ocean."
