U.S. Victims Sue UN Agency for Alleged Support to Hamas, Hezbollah in Landmark Legal Battle

U.S. victims of attacks by Hamas and Hezbollah have filed a major lawsuit against the United Nations Relief and Works Agency (UNRWA), alleging that the UN agency knowingly provided material support to terrorist groups responsible for the October 7, 2023 massacre and other atrocities. The litigation marks a new legal front in the struggle to hold international organizations accountable for their roles in conflict zones where terrorism persists[1][2][3].

Background: October 7 and the Legal Response

On October 7, 2023, Hamas launched a large-scale terrorist attack on Israel, resulting in the deaths of more than 1,200 people, thousands injured, and the abduction of over 200 civilians[3]. Among the victims were U.S. citizens and residents. In the aftermath, families of the victims have sought justice not only against the perpetrators but also against those alleged to have facilitated the attacks through funding or operational support.

Traditionally, international organizations like UNRWA have enjoyed broad legal immunity under the International Organization Immunities Act (IOIA), which parallels the protections given to foreign states under the Foreign Sovereign Immunities Act (FSIA)[2]. However, growing evidence and public pressure have challenged this immunity, especially when it comes to allegations of material support for terrorism.

The Lawsuit Against UNRWA: Claims and Evidence

In June 2024, a group of U.S. victims and their families filed a lawsuit in U.S. federal court against UNRWA, providing extensive new details on how the agency allegedly participated in a billion-dollar money-laundering operation that funded Hamas[1]. The plaintiffs’ legal team claims that over a decade of fraud and corruption diverted humanitarian aid intended for Gaza’s civilians into channels that directly benefited terrorist groups[1].

The lawsuit alleges the following:
– UNRWA was fully aware of, and even facilitated, the diversion of funds meant for civilian aid to support Hamas operations, thereby violating both U.S. and international anti-terrorism laws[1][2].
– Hamas operatives controlled 24 out of 26 leadership positions in the UNRWA employee union, and at least 10% of UNRWA employees were Hamas members[1].
– More than 100 UNRWA employees participated directly in the October 7 terror attack, and some staff members allegedly held Israeli hostages in their homes[1].
– UNRWA’s operational costs and staff size per refugee served were nearly ten times that of the UN High Commissioner for Refugees, raising questions about inefficiency and potential misuse of funds[1].

Legislative Developments: The LIABLE Act

This lawsuit comes as the U.S. Congress debates new legislation—the Limiting Immunity for Assisting Backers of Lethal Extremism (LIABLE) Act—introduced by Senator Ted Cruz and colleagues in April 2025[2]. The bill would allow American victims of terrorism to sue international organizations that provide material support to groups like Hamas and Hezbollah, stripping these organizations of their traditional immunity if they are found to aid terrorist activities[2].

Senator Cruz and other lawmakers have specifically cited UNRWA as a beneficiary of U.S. government waivers, which enabled the agency to send hundreds of millions of dollars into the Hamas-controlled Gaza Strip despite legal prohibitions against material support for terrorism[2]. The legislative effort is part of a broader push to hold not only direct perpetrators but also their enablers accountable in U.S. courts.

Implications and Broader Context

The legal and legislative actions against UNRWA and similar organizations represent a significant shift in international accountability. Previously, victims of terrorism had limited avenues to pursue justice against large institutions shielded by legal immunity. The current lawsuit and the LIABLE Act, if enacted, could set precedents for piercing that shield when evidence suggests complicity in terrorism[2][3].

Legal experts note that U.S. law already allows victims or their survivors to sue private entities for damages resulting from international terrorism, but extending this right to international organizations is unprecedented[3]. The case against UNRWA could serve as a test for how the U.S. judiciary interprets these new legal boundaries and the sufficiency of evidence required to overcome immunity defenses.

Criticism of UNRWA and Ongoing Investigations

UNRWA has faced longstanding criticism for its operations in Gaza and alleged ties to Hamas. Reports have documented that Hamas has deeply embedded itself in civilian infrastructure, including education and social services, sometimes using public facilities for military purposes[1][4]. The lawsuit provides new, detailed evidence of UNRWA’s alleged awareness and involvement in these activities, including the employment of individuals directly implicated in terrorist acts[1].

In parallel to the civil litigation, lawmakers have called for criminal investigations into U.S.-based non-profits that raise funds for UNRWA, arguing that these funds may constitute material support for terrorism under U.S. law[2]. The outcome of these efforts could have far-reaching implications for humanitarian organizations operating in conflict zones with terrorist activity.

Conclusion

As the lawsuit proceeds, its outcome will be closely watched by policymakers, humanitarian organizations, and victims’ advocates worldwide. The case against UNRWA raises fundamental questions about the responsibilities and liabilities of international organizations in war zones, the scope of U.S. anti-terrorism laws, and the effectiveness of oversight mechanisms meant to prevent the diversion of aid to terrorist groups[1][2][3]. The legal battle may ultimately reshape the landscape for humanitarian aid and accountability in the Middle East and beyond.
