Jailed Nobel Peace Prize laureate Narges Mohammadi was in critical condition in a cardiac care unit in ​northwestern Iran on Sunday, two days after she was ‌brought to the hospital from prison, a foundation run by her family said.

Mohammadi’s blood pressure has continued to fluctuate dangerously, and treatment ​has been limited to efforts to stabilise her condition ​through oxygen therapy, the Narges Mohammadi Foundation said ⁠in a statement.

She was transferred from prison to hospital ​in the northwestern city of Zanjan on Friday following a “catastrophic deterioration” of her health, which the foundation said included two episodes of complete loss of consciousness and a severe cardiac crisis.

Mohammadi, who is ​in her 50s, won the Nobel Peace Prize while ​in prison for a campaign to advance women’s rights and abolish ‌the ⁠death penalty in Iran. She suffered a suspected heart attack in late March, her family said.

“Effective treatment for Narges Mohammadi’s conditions is only possible if she is transferred to ​her medical team ​in Tehran,” ⁠the foundation said in its Sunday statement.

Mohammadi was sentenced to a new prison term of 7-1/2 ​years, the foundation said in February, weeks ​before the ⁠US and Israel launched their war against Iran. The Nobel committee at the time called on Tehran to free her immediately.

She ⁠was arrested in December after denouncing the death ​of a lawyer, Khosrow Alikordi; prosecutor Hasan Hematifar told reporters then she had ​made provocative remarks at Alikordi’s memorial ceremony.
