U.S. designates four European Extremist Groups as Terror Groups

The United States on Thursday designated four militant groups based in Germany, Italy, and Greece as foreign terrorist organizations, expanding Washington’s counter-extremism actions in Europe.

The State Department said the designation covers Antifa Ost in Germany, Italy’s Informal Anarchist Federation/International Revolutionary Front, and two Greek groups — Armed Proletarian Justice and Revolutionary Class Self-Defense. The measures take effect on November 20 and impose financial and travel restrictions under U.S. law.

Secretary of State Marco Rubio said the groups follow anarchist or Marxist-inspired ideologies and have been linked to multiple violent attacks. He said the United States aims to disrupt their ability to raise funds, plan operations, and coordinate with like-minded networks.

According to the State Department, Antifa Ost carried out attacks in Germany and Hungary from 2018 to 2023. German intelligence classified it as a violent extremist network in 2024, leading to a series of arrests between late 2023 and 2024.

In Greece, Revolutionary Class Self-Defense claimed responsibility for an explosion at a railway operator in April and for an attack on the labour ministry in 2024. Armed Proletarian Justice said it planted a 2023 bomb near riot-police headquarters in Goudi.

Officials in Italy and Germany did not comment immediately after the announcement. A Greek official, speaking anonymously, said the government rejects all violent extremist activity.

The decision signals the United States’ growing focus on violent non-state groups operating in Europe. U.S. officials said the designations are intended to prevent the organizations from accessing global financial systems and expanding their operational reach.
