Reza Khandan said that health care professionals decided to hospitalize his wife, Nasrin Sotoudeh, because of heart and respiratory problems as well as low blood pressure.

Khandan said Sotoudeh was transferred to a hospital in north Tehran from the notorious Evin Prison earlier on Saturday.

Sotoudeh began her hunger strike in mid-August from her prison cell. She was arrested in 2018 on charges of collusion and propaganda against Iran’s rulers and eventually was sentenced to 38 years in prison and 148 lashes. Under the law she must serve at least 12 years.

During her prison term, Sotoudeh occasionally visited clinics as she suffered chronic gastrointestinal and foot problems.

Earlier this year, the 57-year-old Sotoudeh - known for defending activists, opposition politicians and women prosecuted for removing their headscarves,-held a five-day hunger strike demanding prisoners be released to protect them from the coronavirus.
