TEHRAN, Aug. 5 (Xinhuanet) -- The European Union (EU) here on Friday morning presented the long-awaited comprehensive proposal on the Iranian nuclear issue, state television reported.

    The propo sal was delivered by ambassadors of Britain, France and Germany to Tehran, the EU trio acting as brokers of Iran's nuclear issue for nearly two years, said the report.

    The EU trio promised to present a comprehensive nuclear proposal to Iran in two months during the latest bilateral negotiations in Geneva in late May.

    But the EU did not provide the proposal which includes economic, political and technological incentives on the promised time.

    Iran has threatened earlier this week to resume work of the uranium conversion facilities in the central city of Isfahan under the supervision of the International Atomic Energy Agency (IAEA) to press the Europeans to present the proposal as early as Aug. 1.

    The EU refused to accept the deadline and said they would call for an emergency meeting of the IAEA Board of Governors, urging Tehran not to take the unilateral measure and hinting that Iran's nuclear case could be referred to the UN Security Council.

    Iran's chief nuclear negotiator Hassan Rowhani said on Wednesday that Iran expected to resume the conversion activities on Saturday.

    The EU trio softened its stance on Thursday, saying that they were planning to present the proposal ahead of the scheduled date.

    Iran has suspended its uranium enrichment activities since November 2004 to pave the way for talks with the EU trio to settle dispute over its nuclear program.

    The United States has also accused Iran of using the program to develop nuclear weapons. But Tehran has rejected the accusation and insisted that its nuclear program is for peaceful purposes. Enditem
