Designations of Antifa Ost and Three Other Violent Antifa Groups

Fact Sheet

November 13, 2025

Today, the Department of State announces the designation of Antifa Ost, Informal Anarchist Federation/International Revolutionary Front, Armed Proletarian Justice, and Revolutionary Class Self-Defense as Specially Designated Global Terrorists (SDGTs) and the intent to designate all four groups as Foreign Terrorist Organizations (FTOs), effective November 20, 2025. 

Antifa Ost

Antifa Ost (also known as Antifa East and Hammerbande) is a Germany-based militant group. Antifa Ost conducted numerous attacks against individuals it perceives as “fascists” or part of the “right-wing scene” in Germany between 2018 and 2023 and is accused of having conducted a series of attacks in Budapest in mid-February 2023.
On September 26, 2025, Hungary declared Antifa Ost to be a terrorist organization and added the group to its national anti-terrorism list.

Informal Anarchist Federation/International Revolutionary Front (FAI/FRI)

FAI/FRI is a militant anarchist group that primarily operates in Italy with historical self-proclaimed affiliates across Europe, South America, and Asia. FAI/FRI declares the necessity of the revolutionary armed struggle against nation states and “The Fortress Europe.”
Since 2003, FAI/FRI has claimed responsibility for threats of violence, bombs, and letter bombs against political and economic institutions, including a courthouse and other “capitalist institutions.”

Armed Proletarian Justice

Armed Proletarian Justice is a Greek anarchist and “anti-capitalist” group that has attempted and conducted improvised explosive device (IED) attacks against Greek government targets.
Armed Proletarian Justice claimed responsibility for planting a bomb near the Greek riot police headquarters in Goudi, Greece on December 18, 2023.

Revolutionary Class Self-Defense

Revolutionary Class Self-Defense is a Greek anarchist and “anti-capitalist” group. The group links its actions to broader political and social issues and cites opposition to “capitalist structures,” “state repression,” and solidarity with Palestine.
Revolutionary Class Self-Defense claimed responsibility for two IED attacks targeting the Greece Ministry of Labor (February 3, 2024) and the Hellenic Train offices (April 11, 2025).

Terrorist designations expose and isolate entities and individuals, denying them access to the U.S. financial system and resources they need to carry out attacks.

All property and property interests of designated individuals or groups that are in the United States or that are in possession or control of a U.S. person are blocked. U.S. persons are generally prohibited from conducting business with sanctioned persons. It is also a crime to knowingly provide material support or resources to those designated, or to attempt or conspire to do so.

Persons that engage in certain transactions or activities with those designated today may expose themselves to sanctions risk.  Notably, engaging in certain transactions with them entails risk of secondary sanctions pursuant to counterterrorism authorities.

Today’s actions are taken pursuant to section 219 of the Immigration and Nationality Act and Executive Order 13224.  FTO designations go into effect upon publication in the Federal Register.

Petitioners requesting removal of those designated from the Specially Designated Nationals and Blocked Persons List should refer to the Department of State’s Delisting Guidance page.
