“As for the situation of Iranian citizens who are [in prisons] in the US, we have expressed our concern on this issue from the first day. This topic remains on our agenda, however, naturally, these are different issues (prisoner exchange and a return to the nuclear deal),” he said. The diplomat added that “if the opposite side shows a desire, then an agreement on both issues is possible soon.”
