A religious decree issued by Iran's supreme leader banning nuclear weapons is binding for the Iranian government, the Foreign Ministry said Tuesday, Jan. 15, 2013, suggesting that the edict should end the debate over whether Tehran is pursuing atomic arms. Ministry spokesman Ramin Mehmanparast said the West must understand the significance of Ayatollah Ali Khamenei's edict for Iran, saying "there is nothing higher than the exalted supreme leader's fatwa to define the framework for our activities in the nuclear field."

VIENNA (AP) — A senior U.N. team is embarking on a new try to restart its probe into suspicions that Iran secretly worked on nuclear arms.
The International Atomic Energy Agency team is flying to Tehran and meeting with senior officials there. Team leader Herman Nackaerts says the IAEA hopes to "finalize the structured approach" that would outline what the agency can and cannot do in its investigation.
Nackaerts spoke Tuesday ahead of the departure of his IAEA squad. The U.N. nuclear watchdog agency has tried for more than a year to restart its stalled investigations into allegations that Iran worked on developing such weapons.
Tehran steadfastly denies any such activity and insists that any new agency investigation must be governed by an agreement that lays out the scope of such a probe.
