ISRAEL has drawn up secret plans to destroy Iran’s uranium enrichment facilities with tactical nuclear weapons.

Two Israeli air force squadrons are training to blow up an Iranian facility using low-yield nuclear “bunker-busters”, according to several Israeli military sources.

The attack would be the first with nuclear weapons since 1945, when the United States dropped atomic bombs on Hiroshima and Nagasaki. The Israeli weapons would each have a force equivalent to one-fifteenth of the Hiroshima bomb.

Under the plans, conventional laser-guided bombs would open “tunnels” into the targets. “Mini-nukes” would then immediately be fired into a plant at Natanz, exploding deep underground to reduce the risk of radioactive fallout.

“As soon as the green light is given, it will be one mission, one strike and the Iranian nuclear project will be demolished,” said one of the sources.

Israeli and American officials have met several times to consider military action. Military analysts said the disclosure of the plans could be intended to put pressure on Tehran to halt enrichment, cajole America into action or soften up world opinion in advance of an Israeli attack.

Robert Gates, the new US defence secretary, has described military action against Iran as a “last resort”, leading Israeli officials to conclude that it will be left to them to strike.

Israeli pilots have flown to Gibraltar in recent weeks to train for the 2,000-mile round trip to the Iranian targets. Three possible routes have been mapped out, including one over Turkey.

Air force squadrons based at Hatzerim in the Negev desert and Tel Nof, south of Tel Aviv, have trained to use Israel’s tactical nuclear weapons on the mission. The preparations have been overseen by Major General Eliezer Shkedi, commander of the Israeli air force.

Sources close to the Pentagon said the United States was highly unlikely to give approval for tactical nuclear weapons to be used. One source said Israel would have to seek approval “after the event”, as it did when it crippled Iraq’s nuclear reactor at Osirak with airstrikes in 1981.
