An adviser to supreme leader Ayatollah Ali Khamenei said Wednesday that Iran could accept far-reaching curbs on its nuclear program in exchange for sanctions relief, U.S. media reported.

In an interview with NBC News, Ali Shamkhani said that Tehran could agree to never develop nuclear weapons, give up stockpiles of highly enriched uranium and allow inspectors to nuclear sites — among other steps — if economic sanctions were lifted.

Shamkhani said "yes" in response to a reporter's question on whether Iran would be willing to sign an agreement with the administration of U.S. President Donald Trump, if sanctions were lifted "immediately."
