A report by the New York Times yesterday cited US officials as saying that a major military exercise carried out by Israel earlier this month seemed to be a practice for any potential strike against Iran's nuclear facilities.
A Pentagon official briefed on the exercise said a goal of the practice was to send a message that the Jewish state was prepared to act militarily if diplomatic efforts failed to halt Tehran's production of bomb-grade uranium.
Last month the International Atomic Energy Agency, the UN's atomic watchdog, expressed "serious concern" that Iran is still hiding information about alleged studies into making nuclear warheads and defying UN demands to suspend uranium enrichment.
