Tehran: Iran warned the United States and Israel on Saturday it would be "madness" to attack the country over its nuclear programme.

The comments by government spokesman Gholamhossein Elham came a few days after Iranian missile tests heightened regional tension.

Israel staged an air force exercise last month that stoked speculation about a possible assault on Iranian nuclear sites.

Iran has vowed to strike back at Tel Aviv and US interests and shipping in the region if it is attacked, threatening to close the Strait of Hormuz, conduit for oil.

"We do not imagine that anybody would commit such madness and stupidity...and nobody has the power to make such aggression," state broadcaster Irib quoted Elham as saying.


"The Islamic Republic of Iran is not a threat at all and will not accept any threats," Elham said. Iran has said its nuclear projects are peaceful.

Iran's Foreign Minister Manouchehr Mottaki said he believed Iran's enemies would not want to get involved in a new Middle East crisis by launching strikes against his country.

"The Zionist regime is still involved in the aftershocks of the war with Lebanon," he told the Irna news agency, referring to Israel's 2006 war with Hezbollah. "And the US still does not possess the capacity to enter another crisis in the Gulf region."
