The United States and Iran started a new round of nuclear talks in Rome, Italy on Saturday to resolve their decades-long standoff over Tehran's atomic aims.

Iran's Foreign Minister Abbas Araqchi and US President Donald Trump's Middle East envoy Steve Witkoff will negotiate indirectly through an Omani official who will shuttle messages between the two sides.

Abbas Araqchi, in a meeting with his Italian counterpart ahead of the talks, said Iran has always been committed to diplomacy and called on "all parties involved in the talks to seize the opportunity to reach a reasonable and logical nuclear deal.
