Prime Minister Ehud Olmert warned cabinet ministers Sunday to be wary of making public comments about Iranian President Mahmoud Ahmadinejad and the Islamic Republic's nuclear development program.

Iran issued a warning Sunday telling Israel there would be an imediate retaliation for any Israeli "aggression." Defense Minister Ehud Barak said last week that Israel might be forced to deal with the threat of a nuclear Iran without backup from the U.S. or any other allies.
