TEHRAN: Iran confirmed Tuesday ongoing “negotiations” with the United States over a potential prisoner swap, after a US official said Washington is working to release its detained citizens. The US envoy for Iran, Robert Malley, said on Saturday that President Joe Biden insists on the release of all Americans and will not accept a “partial deal”. Malley called the release of Americans detained in the Islamic republic a “priority” and said that negotiations with Iran have “made some progress,” NBC News reported. Asked about Malley”s remarks, Iran”s government spokesman Ali Rabiei confirmed the talks and said Tehran calls for the release of all Iranian prisoners, not just those held in the US. Iran “is ready to swap all political prisoners in exchange for freeing all Iranian prisoners across the world,” he told reporters at a televised press conference. They include those “who have been detained upon US orders” or at Washington”s request, he added, saying that “the negotiations on this issue are ongoing”. Iran”s foreign ministry spokesman Saeed Khatibzadeh said Monday that Foreign Minister Mohammad Javad Zarif had “put forth a plan to swap all Iranian and American prisoners”, state news agency IRNA reported.
