A diplomatic source had said on Wednesday that Iran is not prepared to resume negotiations on coming back into compliance with the 2015 nuclear deal until Raisi's administration has begun.
Abbas Araqchi, also said on Twitter, that the United States and Britain need to stop linking the exchange of prisoners with the nuclear deal.
"TEN PRISONERS on all sides may be released TOMORROW if US&UK fulfill their part of deal," he added.
