From the BBC:

Israeli Prime Minister Ehud Olmert appears to have come close to admitting that his country has nuclear weapons.

Speaking on German TV, he said Israel did not threaten "any nation with annihilation" while Iran openly threatened to wipe Israel off the map.

Israeli officials later denied it was a change of policy of nuclear ambiguity.
