Iran's Foreign Ministry said on Monday that Israel poses no military threat to Iran, adding that any aggression on Israel's part would spark retaliation and accusing Israel of trying to sabotage relations between Tehran and the International Atomic Energy Agency.
"The Zionist regime [Israel] is less than nothing to pose any kind of threat to Iran," ministry spokesman Mohammad Ali Hosseini told reporters Sunday when questioned about recent comments on Tehran's nuclear program made by Israeli officials.
It was not clear what Israeli threat Hosseini was referring to, but his statement came as Iran continues to defy international demands that it suspends uranium enrichment, a process that can produce fuel for a nuclear reactor or fissile material for a bomb.  
The United States has said it is pursuing diplomatic angles with Tehran for now, but has not ruled out military action as a way to halt Iran's nuclear enrichment, claiming it is using it as cover for weapons development, a charge Iranians deny.
Israel has said it views Iran as a strong threat, but most analysts think any Israeli military operation is unlikely at this point Hosseini warned Israel not to consider military action. In case it does, it will be faced with unprecedented response from Iran, Hosseini said, without elaborating.
He said Israeli threats were geared at preventing a diplomatic solution to Iran's nuclear standoff. Israelis many times have raised such things in order to undermine cooperation between Iran and the (UN) International Atomic Energy Agency, he said.
In 1981, Israel bombed a nuclear reactor in Iraq to prevent Saddam Hussein from developing nuclear weapons. While Israel neither acknowledges nor denies possessing nuclear arms, it is thought to have about 100-200 nuclear warheads, according to a 2006 report by the Center for Nonproliferation Studies at the Monterey Institute of International Studies.
Iran said Wednesday it has stepped up uranium enrichment activities by fully running 3,000 centrifuges at its nuclear plant in the central city of Natanz. It would take some 54,000 centrifuges to fuel a reactor
