Iran’s imprisoned Nobel Peace Prize laureate Narges Mohammadi, 54, has been urgently transferred from prison to a hospital in northwestern Iran after a “catastrophic deterioration” of her health, her foundation said Friday. The Narges Mohammadi Foundation said the Nobel Prize laureate had two episodes of complete loss of consciousness and a severe cardiac crisis.

The hospital transfer comes “after 140 days of systematic medical neglect,” since her arrest on December 12 last year, the foundation said. “This transfer was done as an unavoidable necessity after prison doctors determined her condition could not be managed on-site, despite standing medical recommendations that she be treated by her specialized team in Tehran,” the foundation said.
