The head of the U.N.'s nuclear watchdog met with Iranian officials Thursday in Tehran in the latest effort to resolve long-standing questions about the country's nuclear program.
International Atomic Energy Agency (IAEA) chief Yukiya Amano held talks with the secretary of Iran's Supreme National Security Council, Ali Shamkhani, and was also due to meet with President Hassan Rouhani.
The IAEA said the officials were due to discuss how to more quickly resolve outstanding issues, including "clarification of possible military dimensions" of Iran's nuclear activity.
Iran has long denied working to develop nuclear weapons and said the allegations are linked to faulty intelligence from the United States and Israel.
The IAEA has tried for years to get answers in its probe, including having U.N. inspectors visit the Parchin military site, but has faced resistance from Iran.
