Iran’s Foreign Ministry has announced that it has designated the naval and air forces of all European Union member states as terrorist entities, invoking the principle of reciprocal action.

In a statement issued on Saturday, the Ministry of Foreign Affairs of the Islamic Republic of Iran said the measure was taken in response to what it described as an “illegal and unjustified” decision by EU governments to label the Islamic Revolutionary Guard Corps (IRGC) as a terrorist organization.

The move follows a decision adopted by the European Union on February 19, 2026. Tehran argued that the European action contravenes fundamental principles of the United Nations Charter and international law, emphasizing that the IRGC is an official branch of Iran’s armed forces.

The Foreign Ministry cited Article 7 of Iran’s 2019 legislation titled “Countermeasures Against the Designation of the Islamic Revolutionary Guard Corps as a Terrorist Organization by the United States.” Under the law, any country that follows or supports the United States’ designation of the IRGC may face reciprocal measures from Iran.

Referring to Article 4 of the same legislation, Iran formally identified the naval and air forces of all EU member states as subject to countermeasures and designated them as terrorist organizations under its domestic legal framework.

The statement concluded by asserting that the decision was taken in accordance with Iran’s national laws and in response to what it called a clear violation of international legal principles by European governments.
