London on Wednesday (July 17th) demanded the immediate release of a jailed British-Iranian woman whose husband said she was transferred to the mental ward of a public hospital in Tehran, AFP reported.
The case of Nazanin Zaghari-Ratcliffe has roiled Britain's relations with Iran since her 2016 arrest and subsequent conviction on sedition charges she denies.
"We are extremely concerned about Nazanin's welfare and call for her immediate release," a spokesman for Prime Minister Theresa May said.
"We urge Iran to allow family members to visit her and check on her care."
UK Foreign Office minister Andrew Murrison said Zaghari-Ratcliffe's husband had told him that she was moved to the ward on Monday.
The detention conditions Zaghari-Ratcliffe has described to her family over the phone "are completely contrary to international norms", he said.
Zaghari-Ratcliffe was transferred from Evin prison to Imam Khomeini hospital on Monday, where her father confirmed she is being held by the Islamic Revolutionary Guard Corps (IRGC).
She was arrested in April 2016 as she was leaving Iran after taking her then 22-month-old daughter Gabriella to visit her family, and was sentenced to five years for allegedly trying to topple the Iranian government.
A project manager with the Thomson Reuters Foundation, the media group's philanthropic arm, Zaghari-Ratcliffe denies all charges.
Meanwhile, Iran confirmed on Tuesday that it had arrested a well-known French-Iranian academic without giving any details of her case.
The detention of Fariba Adelkhah, 60, risks increasing tension between Paris and Tehran at a critical moment in efforts to save a landmark 2015 nuclear deal.
