Iran will decide on an offer of nuclear talks made by the United States and five other world powers after reviewing the details, a senior adviser to Iranian President Mahmoud Ahmadinejad said on Thursday. “We will review it and then decide about it,” Ali Akbar Javanfekr told Reuters. Javanfekr’s comments came after U.S. Secretary of State Hillary Clinton said Wednesday that her country would be a “full participant” in talks by major powers with Iran over its nuclear program.
