"The attacker would quickly regret the action," Iranian Foreign Ministry spokesman Mohammad-Ali Hosseini said in response to a question on the possibility of Israel's military strike on Iran's nuclear sites.

According to a report by British newspaper The Sunday Times, Israel has drawn up secret plans to destroy Iran's uranium enrichment facilities with tactical nuclear weapons.

"Such bragging indicates the weakness of the opposite side and would have no impact on Iran's resolve to continue its peaceful nuclear activities," Hosseini said.

He noted that the reported Israeli move came after the confession of the Israel prime minister Ehud Olmert who acknowledged that the Israeli regime possesses nuclear weapons.

"Such statements showed to the public opinion of the world that the Zionist regime is the main threat to the regional and international security and peace," Hosseini was quoted as saying.

Meanwhile, the Iranian Foreign Ministry spokesman said that suspension of cooperation with the International Atomic Energy Agency (IAEA) is not on Iran's agenda.

"Iran's cooperation with the IAEA will be continued as before,"Hosseini said.

After the UN Security Council adopted a resolution on Dec. 23,2006 to impose sanctions on Iran over its nuclear issue, Iran's parliament has passed a bill urging the government to reduce its cooperation with the UN nuclear watchdog IAEA.
