FILE - In this Wednesday Feb. 15, 2012 file photo, released by the Iranian President's Office, claims to show Iranian President Mahmoud Ahmadinejad, second left being escorted by technicians during a tour of Tehran's research reactor centre in northern Tehran, Iran. Iran's denials that it is trying to develop nuclear weapons carry a distinctly hollow ring among its foes as the U.N. nuclear watchdog piles on worries: Complaining about limits on inspection access and reporting that Tehran is expanding its nuclear fuel labs. But, as Israel increasingly weighs the option of a military strike, Western leaders wary of another Middle East conflict may have to pay closer attention to the claims.
