A British-Iranian woman imprisoned in Iran has been transferred to a hospital mental health facility, her husband says.

Richard Ratcliffe says in Britain that his wife, Nazanin Zaghari-Ratcliffe, has been moved to the mental health ward of Iman Khomeini hospital under the control of the Iranian Revolutionary Guard.

“Hopefully her transfer to hospital means that she is getting treatment and care, despite my distrust of just what pressures can happen behind closed doors. It is unnerving when we don’t know what is going on,” he says.

Zaghari-Ratcliffe, 40, was arrested in Iran while traveling with the couple’s young daughter in April 2016 and has been sentenced to five years in prison after being accused of spying, which she and her family vehemently deny.

She and her husband recently ended a hunger strike designed to call attention to her plight. British officials have failed to secure her release despite repeated efforts.

Her father said he visited the hospital in Tehran Tuesday but was not allowed to see his daughter, who has been out of contact with her family.

The Free Nazanin Campaign says in a statement that it does not know what treatment she is receiving or how long she is expected to remain in the hospital.

British officials urged Iranian officials to let her have contact with her family.
