TEHRAN: French-Iranian academic Fariba Adelkhah was jailed anew for breaking house arrest restrictions, an official from the Islamic republic’s judiciary authority said on Sunday.

Her Paris-based support group had on Wednesday announced “with great shock and indignation” her reincarceration, which comes during sensitive talks in Vienna aimed at reviving a 2015 nuclear deal which offered Tehran sanctions relief in exchange for curbs on its nuclear programme.

“Ms Adelkhah... has unfortunately knowingly violated the limits of house arrest dozens of times,” Kazem Gharibabadi, deputy head of the judiciary, was quoted as saying by Mizan Online, the authority’s news agency.

“She has insisted on doing so despite repeated warnings from judicial authorities. So now, like any other prisoner who has violated the same rules... she has been returned to prison,” he added.

Adelkhah, 62, an expert on Iran and Shiite Islam at France’s prestigious Sciences Po university, was arrested on June 5, 2019, at Tehran airport.

She was sentenced in May 2020 to five years’ imprisonment for conspiring against national security, accusations her supporters have always denounced as absurd. In October of that year, she was placed under house arrest with an electronic bracelet.

The French foreign ministry said the reimprisonment “can only have negative consequences on the relationship between France and Iran and reduce confidence between our two countries.”

French President Emmanuel Macron on Thursday called the decision “entirely arbitrary”, adding that “the whole of France” was “mobilised for her release”.

Gharibabadi insisted that Adelkhah is “a citizen of the Islamic republic of Iran”, adding that Tehran “firmly condemns the intervention of other countries in (its) judicial process.”

Iran does not recognise dual nationality so denies French consular staff access to Adelkhah.

“It is very unfortunate that the French authorities... by issuing hasty statements, make baseless and unfounded remarks that are definitely unacceptable,” Gharibabadi said.

She is one of at least a dozen Western nationals believed to be held in Iran who rights groups abroad say are being detained for political reasons to extract concessions from the West.

Talks between Tehran and global powers on the 2015 nuclear deal entered the New Year with positive signals emerging, including the European Union saying on Friday that a deal remained possible.
