WASHINGTON (AP) — Iran would open its nuclear facilities to international inspectors as part of broad negotiations with the United States that could eventually restore diplomatic relations between the adversaries and those talks have the backing of the nation’s supreme leader, Iranian Foreign Minister Javad Zarif said Sunday.Zarif also said the United States and its allies must end their crippling economic sanctions as part of any deal. The Western-educated Zarif again repeated Tehran’s position that it has no desire for nuclear weapons but has the right to continue a peaceful nuclear program.“Negotiations are on the table to discuss various aspects of Iran’s enrichment program. Our right to enrich is nonnegotiable,” Zarif said during an English-language interview that comes amid a significant shift in U.S.-Iranian relations.At the same time, Zarif’s deputy tried to calm hard-liners’ fears at home.
