The International Atomic Energy Agency has confirmed it is resuming talks with Iran next month over its disputed nuclear program.

The U.N. nuclear agency said Friday that talks will begin on December 13th in Tehran.

The last round of talks, held in late August in Vienna, ended with no agreement over the IAEA's request that Iran be more forthcoming about its nuclear program.

In particular, U.N. inspectors want access to Iran's Parchin facility, a military installation southeast of Tehran that they believe may be a testing ground for nuclear weapons.

Iran, facing international sanctions over its nuclear ambitions, says its nuclear aims are peaceful.
