The head of the International Atomic Energy Agency (IAEA) has called for 'trust but verify' in Iran's nuclear negotiations, emphasizing the need for the IAEA to make the terms of any agreement 'credible' and 'verifiable'. The U.S. and Iran are set to hold a third round of discussions on Saturday, focusing on the technical aspects of Iran's nuclear program and political negotiations. The IAEA has not yet been asked to assist in the negotiations, but Director General Rafael Grossi has been in communication with Middle East envoy Steve Witkoff. Grossi also highlighted the need to address Iran's advancements in uranium stockpiles, centrifuge technology, and weaponization capabilities.
