BREAKING: Argentina’s President Javier Milei Declares Muslim Brotherhood Chapters Terrorist Organizations.

Buenos Aires, January 15, 2026.

In a sweeping national security move, Argentine President Javier Milei has officially declared branches of the Muslim Brotherhood operating in the Middle East as terrorist organizations, in a decision announced by the Office of the President on Thursday.

Under the new measure, the Lebanese, Egyptian, and Jordanian chapters of the Muslim Brotherhood have been added to Argentina’s Public Registry of Persons and Entities Linked to Acts of Terrorism and Their Financing (Report effectively outlawing their activities and support networks within Argentina’s jurisdiction.

Government Justification and Scope.

According to the official announcement, the decision was made “in the context of Argentina’s international commitments in the fight against terrorism and its financing” and in compliance with national law.

Argentine authorities stated the move is based on official reports alleging transnational illicit activity, including alleged involvement in terrorism, public calls for violent extremism, and operational or financial links with other terror-designated groups.

The decision was coordinated across several branches of government, including the Ministry of Foreign Affairs, the Ministry of National Security, the Ministry of Justice, and the Secretariat of State Intelligence.

Alignment With International Partners.

Argentina’s designation comes just one day after the United States took a similar step, designating the Egyptian, Lebanese, and Jordanian chapters of the Muslim Brotherhood as global terrorist groups.

Buenos Aires officials highlighted that this alignment strengthens international cooperation against terrorism and financial networks that support it.

Nations including the United States, Israel, Paraguay, the United Arab Emirates, and Egypt have all taken steps recognizing the group, or its affiliates, as terrorist or extremist organizations.

Broader Security Context.

President Milei’s administration has already designated other groups including Hamas and Venezuela-linked criminal organizations as terrorist entities under Argentine law, underscoring his government’s hardline stance on extremist and criminal networks.

Officials argue these designations enhance mechanisms for prevention, early detection, and punishment of terrorism, and aim to ensure such organizations cannot operate freely within Argentina’s borders or exploit financial systems.

Domestic and International Reactions.

Argentina’s action is likely to have diplomatic and geopolitical repercussions.

Some regional governments have supported the move, framing it as a necessary step in combating violent extremism.

However, critics worry that broad designations risk stigmatizing communities and raising tensions with countries where the Muslim Brotherhood or associated movements remain part of the political landscape.
