It's starting to feel like Groundhog Day in Iran: U.N. nuclear inspectors are travelling back to the Islamic state, seeking answers to the same questions that Iran still hasn't answered.

FOX News Radio's Emily Wither has more from our Middle East Bureau:

The IAEA team last visited Iran in August, and while their demands are the same, the climate has changed.  The nuclear inspectors will be pushing again to access the Parchin military complex - the U.N. body suspects Iran of carrying out explosives tests at the site, linked to their controversial nuclear program.

Iran always says no, but the country's leadership may be more willing to cooperate after President Obama's reelection.  Western sanctions are also hurting the economy - big time.

These talks are running alongside efforts to restart negotiations with Iran and six world powers, including the U.S.  They're expected to sit down again early next year.
