A team of United Nations nuclear inspectors is in Tehran seeking to renew efforts to engage Iran over its controversial nuclear program.
The seven-member delegation from the International Atomic Energy Agency arrived Thursday for the first talks with Iran since August.
Chief inspector Herman Nackaerts said the focus of the visit is to resolve outstanding issues related to Iran's possible development of nuclear weapons.
Iran says its nuclear program is peaceful.
The U.N. nuclear agency wants Iran to grant inspectors access to the Parchin military installation southwest of Tehran, which the West suspects is related to possible nuclear weapons development. Nackaerts says his team would “welcome the chance” to visit Parchin, if Iran allows.
Iran says Parchin is a conventional military site.
Earlier talks in August, held in Vienna, ended with no agreement over the IAEA's request that Iran be more forthcoming about its nuclear program.
