The U.N. nuclear watchdog said on Wednesday it had failed to secure an agreement with Iran during the two-day nuclear talks conducted by a team from the International Atomic Energy Agency (IAEA). "During both the first and second round of discussions, the agency team requested access to the military site at Parchin. Iran did not grant permission for this visit to take place," the Vienna-based IAEA said in a statement quoted by Reuters. "It is disappointing that Iran did not accept our request to visit Parchin. We engaged in a constructive spirit, but no agreement was reached," said IAEA Director General Yukiya Amano. Earlier, Iran's envoy to the IAEA, Ali Asghar Soltanieh, told the country's ISNA news agency that Tehran expected to hold more talks with the U.N. agency. But Amano's spokeswoman, Gill Tudor, made clear no further meetings were planned: "At this point in time there is no agreement on further discussions," she said.
