Britain has said that it will grant "diplomatic protection" to Nazanin Zaghari-Ratcliffe, a UK-Iranian dual citizen jailed in Tehran since 2016, citing a lack of due process and access to medical treatment.
Diplomatic protection is a rarely-used mechanism allowing nations to seek protection on behalf of its citizens on the grounds that they have been wronged by another state, according to Britain's foreign office. Ms Zaghari-Ratcliffe has suffered from health issues, including undergoing tests for breast cancer and a series of panic attacks, while her emotional state has worsened during her confinement.
