The teenage children of imprisoned Iranian activist Narges Mohammadi accepted this year's Nobel Peace Prize in the Norwegian capital on Sunday on behalf of the mother they haven't seen in years, reading out a speech she penned from a Tehran prison as her medal rested on an empty chair.

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 renowned for campaigning for women's rights and democracy in her country, as well as fighting against the death penalty.
