Iran and international nuclear inspectors failed to reach agreement on starting a probe into Iran's alleged nuclear weapons programme, a senior International Atomic Energy Agency (IAEA) official said Wednesday after talks between the two sides, dpa reported.
"We must recognize that our best efforts have not been successful so far," IAEA chief nuclear inspector Herman Nackaerts said in Vienna after the tenth round of negotiations since early 2012.
Iran's IAEA envoy Ali Asghar Soltanieh said the discussions on an agreement that would allow access to Iranian nuclear sites, documents and officials were "constructive and intensive."
He added that "the aim of all these elaborations is to bridge the gap towards the conclusion of the text by the next meeting."
