TEHRAN  - Iran will target "32 US bases and the heart of Israel" if it is attacked, the Fars news agency quoted an aide to supreme leader Ayatollah Ali Khamenei as saying on Saturday. "If America and Israel shoot any bullets and missiles against our country, Iranian armed forces will target the heart of Israel and 32 US bases in the region before the dust from this attack has settled," Mojtaba Zolnoor said. Zolnoor is Khamenei's deputy representative for the elite Revolutionary Guards, the force which controls Iran's more potent weaponry, particularly its longer-range missiles capable of striking Israel and US bases in the Gulf. The United States and its top regional ally Israel have never ruled out attacking Iran over its nuclear drive, which the West fears could be aimed at making nuclear weapons. There has been concern an attack against Iran could be imminent after it emerged Israel had carried out manoeuvres in Greece that were effectively practice runs for a potential strike against Iranian nuclear facilities. Government spokesman Gholam Hossein Elham on Saturday dismissed speculation that Iran risked being attacked by the United States, saying that a military strike would be "craziness." The Islamic republic has repeatedly warned of a crushing response to any aggression against its soil.
