Rubio says he's optimistic on eventual Iran nuclear talks, but status of negotiations is unclear

Secretary of State Marco Rubio expressed optimism about potential resumption of nuclear talks with Iran, noting Iran's agreement to negotiate aspects of its nuclear program previously avoided. However, the status of negotiations remains unclear as Iran has stopped communicating with mediators following Israeli threats against Beirut. Intensifying conflict between Israel and Hezbollah has further destabilized an already fragile ceasefire.
