Treasury Says UK-Based, Ynet Says Austrian, FDD Says Egyptian, and No One Has Shown the Document

The Treasury release of record, sb0572, describes Mahmoud al-Abyari only as a United Kingdom-based senior leader of the Egyptian Muslim Brotherhood and Secretary General of the movement’s General Secretariat, designated on 23 July under E.O. 13224 for acting on behalf of the Egyptian chapter, which OFAC listed as a Specially Designated Global Terrorist in January 2026. Treasury says he supported fundraising for Filistin Vakfi and Hayat Yolu, two Turkey-based organisations already sanctioned over Hamas ties. The Foundation for Defense of Democracies, an advocacy organisation that has campaigned for these designations, calls him a London-based Egyptian national and adds that he edits the movement’s weekly, Risalat al-Ikhwan. Ynet and LBC both describe him as a dual Egyptian-Austrian citizen. Ynet further attributes the asset freeze and travel ban to “the White House” on Thursday, which does not match a Treasury-issued action.

No statement from the General Secretariat answering the designation of its own secretary general has surfaced in eight days. What the movement’s official portal did publish, on Friday 31 July, was a condemnation of the targeting of Egyptian territory and of an explosive-drone attack on a vessel off Damietta governorate — the banned organisation presenting itself as a defender of Egyptian sovereignty. Its most recent statement on the file that OFAC is prosecuting ran on 20 July, three days before the designation: acting General Guide Mahmoud Hussein congratulating Hamas on the election of Khalil al-Hayya, praising the participation of constituencies in Gaza, the West Bank, abroad and in prisons as a practical commitment to “shura practice.” Treasury’s case is that the relationship exists. The Brotherhood asserted it voluntarily, in public, first.

Assessment: The nationality gap is not pedantry, it is jurisdiction. A UK-based Egyptian is Washington acting where London has declined to proscribe. An Austrian citizen is Washington designating a national of an EU member state that has banned Brotherhood symbols since 2021 and would owe an answer of its own. Ynet and LBC are the only outlets making that claim and neither shows documentation; the SDN entry lists nationalities and would settle it. Distrust two other things in the aggregation: Ynet’s White House attribution, and the routine collapsing of SDGT and FTO, which are not the same instrument. Three individuals and one entity from the same action remain unnamed by any outlet.
