WASHINGTON, Jan. 10 (Xinhuanet)-- The United States said on Tuesday that it has no plan to attack Iran and remains committed to diplomacy over the Islamic republic's controversial nuclear program.

    "The president (George W. Bush) made it pretty clear, he said previously that Iran is not Iraq," White House spokesman Scott McClellan told a news briefing.

    "We're working with the international community to solve this in a peaceful and diplomatic manner, that's what we've been doing and continue to do," McClellan said.

    McClellan made the remarks after Iran announced it had resumed sensitive atomic research.

    The spokesman also reiterated possibility to refer Iran's nuclear issue to the Security Council of the United Nations.

    "In terms of options ... he (Bush) never takes options off the table," he said, noting that if Iran breaches its international obligations, "there's no other choice but to refer the matter" to the UN Security Council for possible sanctions.

    The United States and the European Union suspect Tehran is trying to develop weapons under cover of a civilian atomic energy program, a charge Iran vehemently denies. Enditem
