Iran's imprisoned Nobel Peace Prize laureate is in 'critical' condition after a heart attack.

Narges Mohammadi's family and lawyers visited her in Zanjan prison twice in the last month, a statement by the Narges Mohammadi Foundation said on X Wednesday, finding that her health condition was dire. She is weak, pale and has lost weight, said the statement.

The report comes after Mohammadi had a heart attack in the prison on March 24, according to a cardiologist she saw soon after, according to the statement.

The statement said that following the heart attack, Mohammadi was unconscious without anyone resuscitating her for over an hour.

Mohammadi is a rights lawyer who won the Nobel Peace Prize in 2023 while in prison. She was arrested in December during a visit to the eastern Iranian city of Mashhad and sentenced to seven more years in prison.
