PARIS, France (AFP) — Prize-winning Iranian human rights campaigner Narges Mohammadi, currently jailed in Tehran's Evin prison as protests grip the country, has not seen her 16-year-old twins for seven years.

She has not met her husband Taghi Rahmani, himself a veteran of Iranian jails but now living in exile in Paris, for the past decade.

In a new restriction in apparent response to the protests, the authorities have now stripped Mohammadi, 50, of her prison telephone cards for the next two months.

She had already been blocked by authorities from telephoning her children Ali and Kiana in France for the past seven months The latest restriction means she cannot even speak to her family inside Iran.

"The system of prisons in Iran is torturing families," Rahmani told AFP in an interview in the French capital.

"It is not just a torture for the prisoner but for the entire family. The children have not heard Narges' voice for the last seven months."

The toughening of her prison conditions come as Iran presses a crackdown against five weeks of protests that have shaken its leadership over the death of Mahsa Amini who was arrested by the notorious morality police.

Mohammadi had already been banned by the Iranian authorities from speaking to Rahmani, an influential opposition figure widely followed on social media, in prison calls.

"If they heard her speaking to me, they would cut the phone," he said.

"They are torturing our children as they have not seen Narges since 2015. I have not seen her since 2010."

'Prisoner of conscience'

In another blow to any hopes the family have of reunification, Mohammadi was this month handed another 15-month prison sentence on charges of inciting protests, and she is now serving a term of at least eight years in prison.

Her sentences have also come with additional punishments, such as an order for 70 lashes and, in the latest conviction, clearing up the municipal garbage once she is finally released.

"She does not participate in any of those case hearings. The judge is not independent, and she has said she will not participate," Rahmani said.

Explaining the telephone card ban he said: "The authorities do not want prisoners spreading information to the outside world."

A former colleague of Nobel Peace Prize-winning campaigner Shirin Ebadi, Mohammadi has campaigned against the death penalty and for justice for protesters killed in a crackdown on November 2019 demonstrations.

She has won numerous international prizes in recognition for her work, including in 2011 the annual Per Anger Prize issued by the Swedish government. She has been tipped as a possible candidate for the Nobel Peace Prize.

Mohammadi's activism has deprived her of her freedom for much of the past decade after being given a string of convictions by the authorities on national security charges.

She was released from prison in October 2020 but then arrested in November 2021 outside Tehran, while attending a memorial for a man killed during the November 2019 protests.

Mohammadi, who suffers from a heart condition, was given a brief break from prison in April for medical reasons but was then transferred back to Qarchak prison outside Tehran and then sent to Evin.

"Narges is now in Evin which is now full of people who have been arrested in the protests. The conditions in Evin and Iranian prisons in general are very deficient," Rahmani said.

Amnesty International describes Mohammadi as a "prisoner of conscience" who has been arbitrarily detained and subjected to torture by the deliberate denial of healthcare for her heart condition.
