Iran will present detailed proposals within the next two weeks aimed at narrowing remaining differences in nuclear negotiations with the United States, a U.S. official said Tuesday.

"Progress was made, ⁠but ⁠there are still a lot of details to discuss," said the official, who declined ⁠to be identified, detailing discussions in Geneva.

"The ​Iranians said they ​would come back in ⁠the ‌next ‌two weeks ⁠with ‌detailed proposals ​to address some ⁠of the ⁠open gaps ⁠in ​our positions.”

Vice President JD Vance said Tehran had not yet acknowledged all of Washington's red lines.

The Omani-mediated talks were aimed at averting the possibility of U.S. military intervention to curb Iran's nuclear program, weeks after the cleric-run state killed thousands of people as it crushed mass demonstrations.
