The International Atomic Energy Agency's Herman Nackaerts spoke Wednesday in Vienna after returning from what the IAEA called "disappointing" talks with Iranian officials.
"We tried to reach agreement on a way forward to resolve all the outstanding issues, and in particular we discussed the possible military dimensions of Iran's nuclear program," said Nackaerts. "We also tried to get access to a site that is relevant for our investigations. So we approached this trip in a constructive spirit, unfortunately we could not get agreement on either of them. So we could not get access, we could not finalize a way forward."
