DUBAI (Reuters) - Iran on Monday ruled out any U.S. preconditions for reviving a 2015 nuclear deal, including the release of American prisoners held by the Islamic Republic while blaming Washington for the slow pace of talks between Tehran and world powers in Vienna.
The lead U.S. nuclear negotiator told Reuters on Sunday the United States was unlikely to strike an agreement with Iran to revive the nuclear pact unless Tehran released four U.S. citizens Washington says it is holding hostage.
