TEHRAN - Any attack by Israel on Iran will blow back on the Jewish state "like thunder," Iran's supreme leader, Ayatollah Ali Khamenei, said on Sunday. Khamenei also said that the international community's suspicion that Iran was seeking nuclear weapons is based on a "lie". If the Israelis "make any misstep or wrong action, it will fall on their heads like thunder," Khamenei said in a speech marking the 1989 death of his predecessor and founder of Iran's Islamic republic, Ayatollah Ruhollah Khomeini. Allegations that Iran was trying to develop atomic bombs were false, he also said. "International political circles and media talk about the danger of a nuclear Iran, that a nuclear Iran is dangerous. I say that they lie. They are deceiving," Khamenei said. "What they are afraid of -- and should be afraid of -- is not a nuclear but an Islamic Iran." He added: "They invoke the term 'nuclear weapons' based on a lie. They magnify and highlight the issue in their propoganda based on a lie. Their goal is to divert minds and public opinion from the (economic) events that are happening in the US and Europe."
