Iranian officials have denied that the country has worked on nuclear weapons. They have declined to answer many of the IAEA's questions.
The six world powers -- the United States, France, Britain, Germany, Russia and China -- have proposed a list of steps Iran should take to clear up the dispute. But diplomats have signaled they don't plan to let unanswered questions about the so-called "possible military dimensions" hold up the broader agreement.

But at other times he and other officials have appeared more open to allowing limited access.
Iranian officials are also eager to show that they are cooperating with the IAEA, and negotiating in good faith for a nuclear deal.
