HELSINKI (AP) — The children of imprisoned Iranian activist Narges Mohammadi are set to accept this year’s Nobel Peace Prize on her behalf in a ceremony Sunday in the Norwegian capital. Mohammadi is renowned for campaigning for women’s rights and democracy in her country, as well as fighting against the death penalty.

Ali and Kiana Rahmani, Mohammadi’s twin 17-year-old children who live in exile in Paris with their father, will be given the prestigious award at Oslo City Hall, after which they will give the Nobel Peace Prize lecture in their mother’s name.

Mohammadi, 51, was awarded the 2023 Nobel Peace Prize in October for her decades of activism despite numerous arrests by Iranian authorities and spending years behind bars. She is currently detained in a prison in Tehran.

At a news conference in Oslo on Saturday, Kiana Rahmani read out a message from her mother, in which the imprisoned activist praised the role international media played in “conveying the voice of dissenters, protesters and human rights defenders to the world.”

“Iranian society needs global support and you, journalists and media professionals are our greatest and most important allies in the difficult struggle against the destructive tyranny of the Islamic Republic government. I sincerely thank you for your efforts, for all you’ve done for us,” Mohammadi said in her note.

Kiana Rahmani said she held little hope of seeing her mother again.

“Maybe I’ll see her in 30 or 40 years, but I think I won’t see her again. But that doesn’t matter, because my mother will always live on in my heart, values that are worth fighting for,” she said.

Mohammadi’s brother and husband told reporters in Oslo that she planned to go on a hunger strike on Sunday in solidarity with the Baha’i Faith religious minority in Iran.

Rahmani’s husband, Taghi, previously said that he hasn’t been able to see his wife for 11 years, and their children haven’t seen their mother for seven.

Mohammadi played a leading role in protests triggered by the death of 22-year-old Mahsa Amini last year while in police custody for allegedly violating the country’s strict headscarf law which forces women to cover their hair and entire bodies.

Narges Mohammadi is the 19th woman to win the Nobel Peace Prize and the second Iranian woman after human rights activist Shirin Ebadi won the award in 2003.

It’s the fifth time in the 122-year history of the awards that the peace prize has been given to someone who is in prison or under house arrest.

The rest of the Nobel prizes are set to be handed out in separate ceremonies in Stockholm later Sunday.
