Iran would blow up the heart of Israel if it was attacked by the Jewish state or the United States, a Revolutionary Guards official was quoted Friday as saying.

Even if one American or Zionist missile hits our country, before the dust settles, Iranian missiles will blow up the heart of Israel, Mojtaba Zolnour said, according to IRNA news agency.

Zolnour is a deputy representative of Supreme Leader Ayatollah Ali Khamenei in the elite Guards force. Iranian officials have previously said Tehran would retaliate in event of an Israeli or U.S. attack.

Earlier this year, a senior commander said Iranian missiles could reach Israeli nuclear sites. Israel is believed to be the only nuclear-armed Middle East state.

Israel has not ruled out military action if diplomacy fails to end a dispute over Iran's nuclear ambitions, echoing U.S. policy, although Washington is engaged in a drive to resolve the issue through direct talks with Tehran.

The West suspects the Islamic state is covertly seeking to develop nuclear weapons, which Iran denies.

The Zionist regime and the United States cannot risk attacking Iran, Zolnour said in the holy Shi'ite city of Qom on Thursday, citing Iranian military and technological advances, IRNA reported. Iran refers to Israel as the Zionist regime.

At talks in Geneva on October 1, Iran agreed with six world powers -- the United States, Russia, China, Britain, France and Germany -- to give U.N. experts access to a newly-disclosed uranium enrichment plant south of Tehran.

Iran and Western powers described talks as constructive and a step forward. However, underlying tension was highlighted before the meeting when Iran test-fired missiles with ranges that could put Israel and regional U.S. bases within reach.

The Geneva talks are expected to win Iran a reprieve from tougher U.N. sanctions, although Western powers are likely to be wary of any attempt by Tehran to buy time to develop its nuclear program.

Senior cleric Ahmad Khatami, leading Friday prayers in Tehran, said the meeting represented a victory for Iran.

The Geneva conference was a very successful one and amounted to a victory for the Islamic Republic, he told worshippers.

Up until the conference they were constantly talking about sanctions and suspension, but when the conference was held there was no talk of either sanctions or suspension, he said, referring to demands that Iran halt sensitive nuclear work.

World powers at the next round of talks aim to press Iran for a freeze on expansion of enrichment as an interim step toward a suspension that would bring it major trade rewards. Iran has repeatedly rejected such demands.
