EU foreign policy chief Kaja Kallas said on Thursday that the bloc’s foreign ministers took a “decisive step” in labelling the IRGC as a “terrorist” group.

The Iranian Foreign Ministry condemned the decision, saying the move was “illegal, political and contrary to international law” as well as a violation of the country’s internal affairs.

It also said Tehran “reserves the right to take appropriate measures within the framework of international law to defend its sovereignty, national security, and the interests of the Iranian nation, and holds the European Union and its member states responsible for the consequences of this action”.
