US Treasury Targets Alleged Muslim Brotherhood and Hamas Financial Support Network with New Sanctions

The United States has imposed a new round of counterterrorism sanctions targeting individuals and entities accused of facilitating financial support for Hamas through a network allegedly linked to the Muslim Brotherhood. The measures, announced by the U.S. Department of the Treasury's Office of Foreign Assets Control (OFAC), are intended to disrupt fundraising operations, charitable front organisations and financial intermediaries that U.S. authorities allege have channelled resources to Hamas despite existing international sanctions.

According to the Treasury Department, the sanctions designate a senior Egyptian Muslim Brotherhood official together with three individuals and three entities that allegedly provided material support to Hamas. U.S. authorities stated that two of the sanctioned organisations operated as sham charitable entities that purported to conduct humanitarian activities while allegedly diverting significant financial resources to Hamas's military wing. As a result of the designations, all property and interests in property belonging to the sanctioned persons and entities that fall within U.S. jurisdiction are blocked, while U.S. persons are generally prohibited from engaging in transactions involving them.

Treasury officials said the action forms part of the United States' broader strategy to dismantle financial networks that enable designated terrorist organisations to obtain funding through seemingly legitimate commercial and charitable structures. Authorities allege that the sanctioned network used charities, fundraising campaigns and affiliated organisations to collect donations before transferring funds through intermediaries in support of Hamas. The Treasury stated that such networks seek to exploit humanitarian causes and charitable giving to conceal the ultimate destination of financial contributions.

The sanctions also underscore the increasingly complex methods employed by terrorist financing networks to evade international financial controls. U.S. authorities allege that the network relied on multiple facilitators operating across different jurisdictions, allowing funds to move through layers of intermediaries before reaching Hamas. Such structures often involve the use of front companies, non-profit organisations, informal money transfer systems and other mechanisms intended to reduce transparency and complicate law enforcement investigations.

Officials further alleged that charitable organisations can be exploited by terrorist financiers to generate legitimacy while providing a vehicle for fundraising activities that appear humanitarian in nature. Although the overwhelming majority of charitable organisations operate lawfully, regulators have repeatedly warned that criminal and terrorist groups may attempt to misuse the non-profit sector because of its international reach, reliance on donations and humanitarian focus. These risks have long been recognised within international anti-money laundering and counter-terrorist financing standards issued by the Financial Action Task Force (FATF), which encourages countries to adopt targeted, risk-based oversight of vulnerable non-profit organisations.

Beyond charitable structures, authorities have continued to identify alternative financial channels that can be used to move funds outside the traditional banking system. Informal value transfer systems, underground money exchanges and, in some cases, digital assets have featured in numerous international terrorism financing investigations. Regulators have responded by strengthening monitoring requirements for financial institutions, virtual asset service providers and money service businesses to improve detection of suspicious financial activity associated with sanctioned organisations.

The latest sanctions build upon a series of U.S. measures taken in recent years against Hamas and organisations or individuals alleged to have provided financial or logistical support to the group. Washington has increasingly focused on disrupting financial facilitators rather than targeting only operational members, reflecting the view that terrorist organisations depend upon extensive financial infrastructure to sustain recruitment, procurement, logistics and operational activities. U.S. authorities have similarly expanded cooperation with international partners to identify cross-border financial networks and improve intelligence sharing relating to terrorist financing risks.

For financial institutions, the designations reinforce the importance of maintaining effective sanctions screening programmes, beneficial ownership verification, enhanced customer due diligence and ongoing transaction monitoring. Institutions operating internationally are expected to identify customers connected with designated individuals or entities, detect unusual fundraising activity, and submit suspicious transaction reports where appropriate. Charities, non-profit organisations and payment service providers also face heightened expectations to implement governance controls capable of preventing the diversion of funds for terrorist purposes while ensuring that legitimate humanitarian assistance can continue to reach intended beneficiaries.

The Treasury Department indicated that disrupting financial support networks remains a central element of U.S. counterterrorism policy. By targeting individuals, charities and commercial entities alleged to facilitate fundraising and financial transfers, authorities aim to limit Hamas's ability to obtain resources through international financial systems and reduce the capacity of associated networks to circumvent sanctions using seemingly legitimate structures.
