Jerusalem - Israel's deputy defence minister denied on Saturday that Israel was in talks with the United States to use Iraqi airspace as part of possible plans to attack Iranian nuclear sites.

Britain's Daily Telegraph, citing an unnamed senior Israeli defence official, said on Saturday that Israel had sought permission from the US Pentagon to be able to use an "air corridor" in Iraq in the event that the Jewish state decided to launch air strikes on Iranian nuclear facilities.

"We are planning for every eventuality, and sorting out issues such as these (airspace passage) are crucially important," the Daily Telegraph quoted the Israeli official, who spoke on condition of anonymity, as saying.

"If we don't sort these issues out now we could have a situation where American and Israeli war planes start shooting at each other," he added, according to the newspaper's Web site.

Asked if Israel had turned to the U.S. to use Iraqi airspace in any possible attack, Ephraim Sneh told Israel Radio: "No such approach has been made -- that is clear."

"Those who do not want to take political, diplomatic, economic steps against Iran are diverting attention to the mission we are supposedly said to be conducting," Sneh said.

"(They) are anxious to spread the idea that we are planning to attack Iran in order to absolve themselves of the need to do the things that have been requested of them," he added.

Israel and the West accuse Iran of seeking to develop nuclear weapons under the guise of a civilian atomic power programme, which Tehran denies.

Iran has said it wants to negotiate with the Europeans and even the United States but has refused to halt its nuclear enrichment activities as a pre-condition for talks.

Israel, widely believed to have the Middle East's only nuclear arsenal, sent warplanes to bomb an atomic reactor in Iraq in 1981.

Neither Israel nor the United States has ruled out military force on Iran, although Washington says its priority is to reach a diplomatic solution.

Israeli strategic analysts have said it would go against Israeli military doctrine to seek U.S. permission for any possible strike on Iran given the need for total secrecy.

U.S. Vice President Dick Cheney said on Saturday that the United States and its allies must not allow Iran to become a nuclear power.

The five permanent members of the U.N. Security Council plus Germany will meet in London next week to discuss possible further steps in addition to U.N. sanctions barring the transfer of nuclear technology and know-how that were imposed in December.
