A delegation from the International Atomic Energy Agency (IAEA) on Wednesday held the first round of talks with Iranian officials to discuss an action plan to resolve the nuclear dispute, the official IRNA news agency reported.

The three-hour marathon talks was held at Iran's Supreme National Security Council (SNSC) and the two sides will continue negotiations until Thursday, IRNA said.

None of the relative officials made any comments so far, the report said, adding that the results of the talks are to be declared on Thursday afternoon.

The IAEA delegation was led by its deputy head for safeguards Olli Heinonen, while the Iranian team was chaired by Deputy Secretary of the SNSC for International Affairs Javad Vaeedi.

The IAEA team arrived in Iran on Wednesday morning in a bid to draw up a framework to resolve the dispute over the country's nuclear program.

The team is expected to hold talks with Iran's top nuclear negotiator Ali Larijani during its three-day stay in Iran. The talks would be within the frameworks of the Non-Proliferation Treaty (NPT) and the IAEA safeguards, according to IRNA.

The idea to draw up the framework was put forward by Larijani last month when he was in Madrid, Spain for talks with the European Union foreign policy chief Javier Solana about Iran's nuclear program.

Late last month, in a meeting with the IAEA Director General Mohamed ElBaradei in Vienna, Larijani invited a delegation from the IAEA to visit Iran and hold talks with Iranian officials over drawing an action plan to put an end to the stalemate between Iran and the UN nuclear watchdog.
