Tehran, Nov 29 (DPA) Iran has again warned that it would blockade the oil export route in the Persian Gulf if its nuclear sites were attacked, Iranian media reported Saturday.”We are capable of blockading the Strait of Hormuz in the Persian Gulf and whoever does not believe this should … see what happens in reality,” Navy Commander Admiral Habibollah Sayari said.

Iran’s paramilitary Revolutionary Guards had several times in the past warned that if Israel carried out its plan to attack the country’s nuclear sites, Iran would block the Strait of Hormuz at the mouth of the Persian Gulf through which an estimated 20 percent of the world’s daily oil supply passes.

Such a blockade could trigger a worldwide energy crisis.

Admiral Sayari added that any aggressor should not forget that 2,000 km of the Persian Gulf coast belonged to Iran, making the country capable of taking various initiatives.

President Mahmoud Ahmadinejad has in the past also warned that the country would be justified in using all options in the case of an attack, including using controls on oil supplies as a weapon.

Israel and the US have stated that a military strike against Iran would not be ruled out if the Islamic state did not suspend its controversial nuclear projects. Both countries believe Tehran is secretly working on an atomic bomb despite Iranian claims of pursuing a solely civil nuclear programme.
