The head of the United Nations nuclear watchdog agency acknowledged Thursday, December 6 that inspectors had made no progress in a yearlong effort to determine whether Iran had conducted research needed to build an atomic bomb, The Los Angeles Times reported. “We have intensified our dialogue with Iran this year, but no concrete results have been made yet,” Yukiya Amano, head of the International Atomic Energy Agency, said. Inspectors from the IAEA are expected to meet Iranian officials in Tehran next week to seek a resumption of their inquiry on the possible military dimensions of Iran’s nuclear program. The IAEA first reported in November 2011 that intelligence suggested Iran had conducted research that could help it develop a nuclear weapon. The U.S. representative to the IAEA, Robert Wood, last week issued Tehran a March deadline to begin cooperating with U.N. inspectors.
