As President Trump expresses growing concern about the humanitarian situation in Gaza, the leader of an aid group backed by Israel and the United States resigned on Monday, just one day before food trucks started making deliveries.

Conditions in Gaza have grown increasingly desperate since March, when Israel sealed off the Palestinian territory from receiving food and other critical supplies. Israel has claimed that Hamas is stealing aid from the United Nations, which forcefully rejects the accusation and accuses Israel of instead trying to use food as leverage.

Critics also say Israel's plan will force Palestinians to leave northern Gaza, as the food centers are all in the south of the enclave.

The Gaza Humanitarian Foundation is running the Israel-approved system of delivering food aid through private contractors.

Resignation at Gaza aid organization

The organization's executive director, Jake Wood, resigned on Sunday and suggested the group's neutrality was in jeopardy. His resignation came after the New York Times published reports linking the organization to members of Israel's military and business sector.

“I am proud of the work I oversaw, including developing a pragmatic plan that could feed hungry people, address security concerns about diversion, and complement the work of longstanding NGOs in Gaza,” said Wood in a statement.

“However, it is clear that it is not possible to implement this plan while also strictly adhering to the humanitarian principles of humanity, neutrality, impartiality, and independence, which I will not abandon,” he added.

He also urged Israel, which has begun allowing some aid into Gaza, "to significantly expand the provision of aid into Gaza through all mechanisms."

Deliveries start

The Gaza Humanitarian Foundation dismissed Wood, slamming "those who benefit from the status quo" who have "been more focused on tearing this apart than on getting aid in."

"We will not be deterred. Our trucks are loaded and ready to go," the group said.

The organization started making deliveries on Monday, and it has pledged to feed 1 million Gazans by the end of the week.

This all comes as Israel faces mounting isolation over its escalating siege of Gaza, where many are at risk of starving and over 53,000 people have already died since Hamas' October 7, 2023, assault that killed 1,200 Israelis and led to 250 being taken hostage.

President Trump has also distanced himself from Israel in recent weeks, expressing concern about hunger in Gaza and calling for the conflict to end as soon as possible.

“Israel, we’ve been talking to them, and we want to see if we can stop that whole situation as quickly as possible," Trump told reporters on Sunday as he prepared to board Air Force One.
