The Institute for the Study of Global Antisemitism and Policy says the sanctions reinforce the need for coordinated international action against the financial and institutional networks supporting extremist movements
NEW YORK, NY — July 24, 2026 — The Institute for the Study of Global Antisemitism and Policy (ISGAP) commends the U.S. Department of the Treasury for imposing sanctions against a senior Egyptian Muslim Brotherhood official and individuals and entities accused of providing material support to Hamas.
The Treasury Department announced today that its Office of Foreign Assets Control has designated Mahmoud al-Abyari, a senior United Kingdom-based Egyptian Muslim Brotherhood leader, alongside entities described by the Department as Hamas fundraising fronts and an underground financial network operating through Turkey.
Dr. Charles Asher Small, Founder and Executive Director of ISGAP, said: “This crucial action exposes the transnational financial and institutional infrastructure connecting the Muslim Brotherhood, Hamas and the organizations that sustain them. For too long, governments have examined charitable, educational, political and commercial activities in isolation, rather than as elements of a broader influence network. We commend the Treasury Department for following the evidence and urge allied governments to strengthen intelligence cooperation, investigate Muslim Brotherhood-affiliated networks within their jurisdictions and ensure that charitable or civic structures cannot be exploited to finance terrorism or advance extremist ideologies.”
ISGAP has conducted extensive research into the Muslim Brotherhood’s methods of strategic entryism across Western societies, including its activities within higher education, civil society, political institutions and charitable networks. Its research examines how interconnected organizations can use legitimate institutional platforms to build credibility, influence public discourse and advance ideological objectives.
ISGAP’s policy recommendations include closer investigative and intelligence coordination between allied governments, stronger foreign-funding disclosure requirements for universities and civil-society organizations, enhanced scrutiny of charitable and nonprofit financial networks, and targeted legal action where independently verified evidence establishes support for terrorism or other unlawful activity.
