Tehran has designated Argentina's navy and air force as "terrorist organizations," Iran's Foreign Ministry said on Wednesday, in a reciprocal move following Buenos Aires' designation of Iran's Islamic Revolutionary Guard Corps as a terrorist entity in April.
Argentina had designated the IRGC as a terrorist organization, following a push from US President Donald Trump's administration for allies to do so.
Iran's Foreign Ministry said in a statement on Wednesday that Tehran considers the Argentinian air force and navy terrorist organizations "based on the principle of reciprocity."
Iran places blame for decision on Buenos Aires
"It is evident that the responsibility for all consequences arising from this matter will lie with the Argentine government," the ministry added, without elaborating. It made no mention of Argentina's army.
In a statement on Wednesday, Argentina's foreign ministry said it "categorically rejects" Iran's decision.
Argentina said in April that the measure it took against Iran's IRGC was due to its backing for Lebanon-based Hezbollah, which Buenos Aires blames for the deadliest bombing in the South American nation's history, a 1994 attack on the AMIA Jewish community center in the Argentinian capital that killed 85 and injured hundreds.
