South Korea said on Monday it is working with all parties involved in unfreezing Iranian funds worth $6 billion, which once released will trigger a carefully choreographed deal between arch foes the United States and Iran to swap detainees. Once the funds are transferred to Qatar, which mediated the deal during months of talks, five U.S. dual nationals who were imprisoned in Iran are expected to leave Tehran for Doha from where they will travel to the United States. In return, five Iranians detained in the U.S. will be released so they can travel to Iran. Iranian officials and Iran's state news agency have said one of those detainees is expected to remain in the United States. The precise timing of the fund transfer has yet to be publicly announced.
