Argentina has officially listed the branches of the Muslim Brotherhood in Egypt, Jordan, and Lebanon as terrorist organizations, the government of President Javier Milei said in a statement on Thursday, a day after the United States took similar action.

The move is part of Buenos Aires’ broader effort to strengthen national security and align with international partners in combating terrorism and its financing.

The presidency said the chapters in Egypt, Jordan, and Lebanon were added to Argentina’s official registry (RePET), which is used to monitor and restrict groups and individuals linked to terrorism under national law.

The statement said the decision was made “in line with Argentina’s international commitments in the fight against terrorism and its financing, and in compliance with national regulations.”

Officials explained that the designation was based on reports alleging transnational illicit activities, including acts considered terrorism, public calls for violent extremism, and operational or financial links with other terror-designated groups, all of which could pose security risks to Argentina.

The government said the measure aims to strengthen prevention, early detection, and sanction mechanisms and to block funding or support for extremist networks.

Argentina’s decision, coordinated across the presidency, Ministry of Foreign Affairs, Ministry of Security, Justice Ministry, and Secretariat of Intelligence, followed the Trump administration’s designation of the same Brotherhood chapters as global terrorist actors. It also aligns with similar policies adopted by other Western governments to disrupt extremist networks.

Milei’s government described the move as consistent with Argentina’s commitment to international counter-terrorism cooperation and broader security policy priorities.

According to the statement, the presidency reaffirmed Argentina’s determination to identify and confront groups it sees as threats, noting previous actions such as designating Hamas as a terrorist organization and taking measures against other transnational criminal networks.

The Muslim Brotherhood was founded in Egypt in 1928 and was banned there in 2013. Saudi Arabia followed in 2014, labelling the Brotherhood a terrorist organization and warning it posed risks to national security and regional stability.

Other Gulf states, including the United Arab Emirates and Bahrain, have taken similar steps. Jordan banned the Brotherhood in April 2025, citing legal and security concerns.

Outside the Arab world, Russia has designated the Brotherhood a terrorist organization since 2003, while Austria has imposed restrictions on affiliated groups under anti-extremism laws.
