Argentina immobilized an Iranian Mahan Air cargo plane on Sunday that was leased to a Venezuelan state-owned airline, according to Iranian media and confirmed by Argentine Security Minister Fernandez Anibal.
The flight was en route from Mexico and landed in Argentina on Sunday.
The passports of five Iranian passengers traveling on the plane were confiscated, some of whom are allegedly linked to the IRGC, according to Iran International, a Saudi-sponsored, London-based Iranian news television station.
The five passengers were identified as Mohammad Khosravi Aragh, Gholamreza Ghasemi, Mahdi Mouseli, Saeid Valizadeh and Abdolbaset Mohammadi.
The US imposed sanctions on Mahan Air after it suspected that it was providing support to the IRGC.
Venezuelan President Nicolas Maduro is currently visiting Iran, and the two nations signed a 20-year cooperation deal on Saturday.
This is a developing story.
