The move follows Argentina's decision in April to classify Iran's Islamic Revolutionary Guard Corps as a terror organisation.
Iran's foreign ministry on Wednesday designated the Argentine Navy and the Argentine Air Force as terrorist organisations, according to The New Indian Express. The decision was made on the principle of reciprocity following similar actions taken by Buenos Aires.
In late March, Argentina designated Iran's Islamic Revolutionary Guard Corps (IRGC) as a terror organisation. Buenos Aires cited the IRGC's support for the Lebanese militant group Hezbollah, which it holds responsible for a 1994 attack on the AMIA Jewish community centre that killed 85 people and injured hundreds.
The Iranian foreign ministry stated that the two Argentine military branches are subject to a 2019 law that allows for retaliation against any state that designates its military forces as terrorist organisations. The ministry said the Argentine government would be responsible for all consequences resulting from this matter.
It is not immediately clear what practical effect this designation will have. The announcement did not mention the Argentine army.
Earlier this month, Iran designated the UK's MI6 as a hostile group and the Royal Navy and Royal Air Force as terrorist organisations. This occurred after the UK designated the IRGC as a terror organisation in July.
