An initial round of talks on Iran's nuclear programme ended in Tehran on Wednesday between Iranian officials and a delegation from the International Atomic Energy Agency (IAEA) headed by IAEA deputy director Olli Heinonen, state news agency IRNA reported, according to DPA. No results have been disclosed about the three-hour meeting, IRNA said, adding that the second round of talks would be held on Thursday. Initial results are expected to be announced on Thursday afternoon. The Iranian delegation was headed by Javad Vaeidi and Mohammad Saeidi, deputies of the National Security Council and Iranian Atomic Energy Organization respectively, as well as Iran's IAEA envoy Ali- Asqar Soltanieh. There were no reports from a separate meeting between Heinonen and Iran's chief nuclear negotiator Ali Larijani, which was scheduled to be held before the main meeting. Heinonen arrived in Tehran early Wednesday accompanied by three other IAEA officials in charge of safeguard operations, legal issues and external policy coordination. Heinonen and his team were reportedly not scheduled to visit Iran's nuclear sites in the centre of the country but were only to hold talks in Tehran.
