Meanwhile, UK downplays Iranian state TV report on Nazanin Zaghari-Ratcliffe’s possible release from prison.
An unnamed official quoted by Iranian state TV said earlier on Sunday that a deal made between the US and Tehran involved a prisoner swap in exchange for the release of $7bn in frozen Iranian funds.
The state TV report, quoting the unnamed Iranian official, also said British-Iranian national Nazanin Zaghari-Ratcliffe would be released once Britain had paid off a debt on military equipment owed to Tehran.
A British Foreign Office official played down that report.
Iran state TV had quoted the official as saying: “The Americans accepted to pay $7bn and swap four Iranians who were active in bypassing sanctions for four American spies who have served part of their sentences.” It did not name the Iranians that Tehran sought to be freed.
