Experts from the U.N.’s nuclear watchdog are in Iran and will again seek access to a military complex in the country where it is widely suspected that Iranian nuclear scientists conducted tests related to nuclear detonations. Iranian Foreign Ministry Spokesman Ramin Mehmanparast expressed opposition to providing the IAEA inspectors access to the Parchin facility, and lashed out at recent U.S. sanctions designed to encourage Iran to increase transparency around its atomic program. Analysts have expressed difficulty reconciling Mehmanparast’s statements with reports emphasizing progress in negotiations aimed at resolving the crisis around suspected clandestine nuclear weaponization work by Iranian scientists.
