As world powers outline multi-billion-dollar plans to rebuild Gaza, newly obtained documents reveal that Hamas has long run a coordinated effort to penetrate and influence NGOs in the war-torn enclave — contradicting years of denials from major humanitarian organizations.

On Wednesday, NGO Monitor — an independent Jerusalem-based research institute that tracks anti-Israel bias among nongovernmental organizations — released a new study revealing how Hamas has for years systematically weaponized humanitarian aid in Gaza, tightening its grip over foreign NGOs operating in the territory and exposing patterns of complicity and collaboration that contradict the groups’ persistent denials.

While international media has repeatedly accused Israel of unfairly and illegally targeting humanitarian NGOs, Israeli officials have long argued that many of these groups have been infiltrated and manipulated by Hamas, the Palestinian terrorist group that has ruled Gaza for nearly two decades — with the extent of NGO involvement far deeper than their public statements suggest.

Dozens of internal Hamas documents are now being published, providing systematic evidence and even detailing the officials tasked with coordinating and overseeing the Islamist group’s interactions with international NGOs.

According to the documents, Hamas officials designated specific points of contact with “highly respected” international NGOs, including Doctors Without Borders, Oxfam, Save the Children, and the Norwegian Refugee Council.

Referred to as “guarantors,” these Hamas-approved senior officials at each NGO allowed the terrorist group to closely oversee activities, influence decision-making, and circumvent restrictions imposed by some Western governments on direct engagement with Hamas.

Gerald Steinberg, founder and president of NGO Monitor, said the newly released study offers a crucial guide for the US and its allies to vet aid partners, emphasizing the need to carefully screen NGOs to prevent a repeat of Hamas’s domination of Gaza’s reconstruction efforts.

“This research is timely and highly consequential,” Steinberg said in a statement. “Governments and international organizations are planning to provide billions of dollars for the rebuilding of Gaza, and will partner with numerous NGOs to reconstruct infrastructure, provide municipal services like utilities and education, and probably distribute cash payments.”

“We now know which NGOs and their local affiliates have been propping up the Hamas terror regime,” he continued. 

The study also found that at least 10 “guarantors” — senior NGO officials — were not just Hamas-approved, but were also members, supporters, or employees of Hamas-affiliated authorities, who leveraged their positions in numerous NGOs to create Hamas-approved beneficiary lists for UN and other aid programs.

According to one of the obtained internal documents, Hamas conducted extensive surveillance of NGO officials in Gaza, noting that the “guarantors” across 48 NGOs “can be exploited for security purposes” to infiltrate foreign organizations and listing the names and personal details of 55 individuals already serving in those roles.

The document also explicitly outlines the terrorist organization’s intent to further develop or compel “guarantors” to serve as intelligence assets.

The findings appear to corroborate the concerns of many experts and Israeli officials, who have long said that Hamas steals much of the aid flowing into Gaza to fuel its terrorist operations and sells the remainder to Gaza’s civilian population at an increased price. Jerusalem has also said that aid distribution cannot be left to international organizations, which it accuses of allowing Hamas to seize supplies intended for the civilian population. According to UN data, the vast majority of humanitarian aid entering Gaza during the Israel-Hamas war was intercepted before reaching its intended civilian recipients.

With NGOs in Gaza — both local and international — required to secure Hamas’s approval to provide services and run projects, the report shows the group wields veto power over humanitarian operations, allowing it to control, manipulate, and exploit aid to advance its political and military objectives.

“NGO Monitor’s groundbreaking report proves that Hamas controls all humanitarian operations in Gaza, on an institutional level and an individual one,” Naftali Shavelson, NGO Monitor international spokesperson, said in a statement.

“There is no NGO freedom of operation in Gaza. And most crucially, never once did NGOs say anything about this Hamas infiltration,” he continued. “If anything, they issued statements blaming their inhibited operations on Israel – thus ignoring the problem and allowing Hamas to continue harming Gazans.”
