What’s at Stake in the Iran-U.S. Nuclear Talks

A third round of talks between Iran and the United States over Tehran’s nuclear activities concluded Saturday after several hours of indirect negotiations, partly in writing, between senior officials and teams of technical experts from both sides.

Abbas Araghchi, Iran’s foreign minister, said in an interview with Iran’s state television that the talks were “very serious” and focused on details of a potential agreement. He said disagreements remained between Tehran and Washington, but that he was “cautiously optimistic that we can progress.”
