Iran, whose nuclear facilities are under threat of possible Israeli military strikes, proposed Wednesday that a 150-nation conference convening in the fall ban such attacks.

Iran says the proposal, revealed to The Associated Press by diplomats and confirmed by a senior Iranian envoy, is not linked to veiled threats by Israel of an attack as a last resort if the international community fails to persuade Tehran to freeze its nuclear activities.

Instead, all of the diplomats said the Iranian initiative seeks support for a generally worded document prohibiting all armed attacks against nuclear installations anywhere, when 150 nations convene for the September general conference of the International Atomic Energy Agency.

"We are not worried about Israel," said Ali Asghar Soltanieh, Iran''s chief envoy to the IAEA. "Nobody dares to do anything against Iran."

He said an Iranian resolution will seek a worldwide ban on such attacks as "a matter of principle."

"I think this is an urgent concern for all of the international community," he said. "All member states will support the idea."
