Iran is demanding the closure of a multiyear probe by the United Nations atomic agency into its nuclear program as a condition for restoring the 2015 nuclear deal, diplomats said, a major hurdle blocking an agreement.
Negotiators from the U.S., Iran, the European Union and other parties to the deal resumed talks in Vienna on Thursday aimed at restoring the 2015 agreement. The negotiations seek to agree the steps Washington and Tehran must take to return to compliance with the deal’s terms.
