The Swiss charge d'affaires in Tehran was summoned to the Foreign Ministry Tuesday over mistreatment of the US officials in regards to an Iranian woman kept in a US prison, IRNA reported.
During the meeting, a Foreign Ministry official expressed Tehran's protest to the Swiss envoy over mistreating Sharzad Mirqolikhan in a US prison.
Switzerland serves as the protector of US interests in Iran as Tehran-Washington relations were severed after the 1979 Islamic Revolution in Iran.
The Iranian official told the Swiss diplomat that Tehran was also calling for US officials' explanation over the recent reports that the mother-of-two was deprived from basic health and Hygienic facilities and was living under death threats in jail.
Expressing deep concern of Mirqolikhan's family over her living conditions in prison, the Iranian official told the Swiss envoy that she was also deprived of having telephone contacts with her family in Iran and that prison officials had ignored her protests over the issue.
The Iranian side also said that Tehran expected Washington to act as it claims of being a so-called advocate of human rights and respect rights of others.
Mistreating prisoners has always been a problem in the US, the Iranian official said.
The Swiss diplomat promised, in return, to receive a proper response from the US side about the possibility of meeting of the prisoners with their family members.
He stressed that he would convey Tehran's deep concern and protest over the issue, the case of Ms. Mirqolikhan in particular, to Washington.
