The Argentine judiciary has decided to renew the passports of five Iranian crew members of a Venezuelan cargo plane that was detained for a week in Argentina as Buenos Aires is investigating their possible links to the Iranian Revolutionary Guards, according to authorities.

On Monday, an Argentine federal judge ordered an extension of their passport detention by 72 hours, knowing they were currently in a hotel.

They were delivered to Argentina, where they arrived on June 6, on a Boeing 747 owned by the Venezuelan company Emtrasur, which was formerly owned by the Iranian company Mahan Air.

The plane has been banned from flying since Wednesday while at Ezeiza Airport in Buenos Aires after it tried unsuccessfully to fly to Uruguay.

On Monday, Argentina’s security minister, Anibal Fernandez, said after the plane’s landing, “information was received from foreign organizations warning that some of the crew belonged to companies associated with the Islamic Revolutionary Guard Corps,” a military arm of the Islamic Republic of Iran.

In a statement from the Minister of Radio Perville, the Minister said that routine inspections revealed “unfounded things. They stated that the crew size was smaller” leading to the “opening of an investigation which is still ongoing”.

At the end of the week, sources in the Argentine immigration service said that the detained passports could be returned and that the crew could leave the country at any time on a scheduled flight. In the meantime, however, the “Delegation of the Argentine-Israeli Association” asked the judiciary to launch an investigation on behalf of the Israeli community in the country.

The court granted the request and decided to extend the passport quarantine for 72 hours, as well as to ban the flights of the aircraft loaded with spare parts for cars, due to “reasonable suspicion that the declared intention to enter (into the country) is not real.”

Due to Interpol red notices against Iranians accused of being involved in the 1994 bombing of an Argentine Jewish community center that killed 85 people and injured 300, Buenos Aires fears the arrival of Iranian travelers to Buenos Aires.

According to the minister, no red notices were issued to any of the crew members.

In Tehran on Monday, Iran’s foreign ministry said the plane’s issue was part of a “propaganda operation” against Tehran at the height of tensions between the Islamic Republic and Western countries over the nuclear dossier.

And the Islamic Revolutionary Guard Corps, in particular the Al-Quds Force, which includes its elite forces, is on the list of “foreign terrorist organizations” of the United States. Tehran demands that the Revolutionary Guards be removed from this list.
