Iranian security forces have "violently arrested" Nobel Peace Prize winner and women's rights activist Narges Mohammadi, her foundation has said.
The Narges Foundation said her brother confirmed Ms Mohammadi was detained in the eastern city of Mashhad, along with other activists.
It has called for the immediate release of the 53-year-old and the activists detained alongside her. Iran does not appear to have commented.
Ms Mohammadi was awarded the 2023 Nobel Peace Prize for her activism against female oppression in Iran and promoting human rights.
In December 2024, she was given a temporary release from jail for three weeks on medical grounds, after being held in Tehran's notorious Evin prison since 2021.
