TEHRAN, Feb. 4 (Xinhuanet) -- Iranian President Mahmoud Ahmadinejad ordered an end to snap inspection of its nuclear facilities from Sunday in reaction to the U.N. nuclear watchdog's decision to report Iran to the U.N. Security Council, state television announced late Saturday.

    Ahmadinejad ordered Iran's Atomic Energy Organization to stop voluntary implementation of the additional protocol to the nuclear Non-Proliferation Treaty and other cooperation from Sunday, the report said.

    The additional protocol, signed by Iran's former government but never ratified by the parliament, allows short-notice inspection by the International Atomic Energy Agency (IAEA).

    Iran's Majlis (Parliament) passed a law last November which requires the government to cease all voluntary confidence-building measures if the country's nuclear case were referred to the UN Security Council.

    Iran suspended all uranium enrichment related activities and allowed snap inspection of its nuclear sites to pave the way for nuclear negotiation with the EU trio of Britain, France and Germany in late 2004.

    The emergency meeting of the IAEA board of governors adopted a resolution on Saturday in Vienna to report Iran's nuclear issue to the UN Security Council after Tehran resumed nuclear fuel research last month. Enditem
