A senior Iranian official has warned that any aggression against his country would trigger a "decisive and full-scale response", PressTV reported.
"I think that America and Israel are fully aware what kind of result such a wrong judgment will entail," said Alaeddin Boroujerdi, the head of parliament's National Security and Foreign Policy Commission, in Japan on Monday.
"That kind of erroneous judgment poses a threat to the entire Middle Eastern region and the world," he added.
"Israel showed its military power sufficiently in the 22-day war," he explained. "If (an Israeli attack) occurred, then the Islamic Republic of Iran will respond in a very full-scale and very decisive way."
Boroujerdi' remarks come after the US Vice President Joe Biden said Washington would not stop Israel if it wants to bomb Iran.
Israeli officials have frequently threatened Iran with military action to halt its nuclear program. Tel Aviv and its Western allies have been accusing the Islamic Republic of developing nuclear weapons.
Tehran however dismisses the allegations and asserts that as a signatory to the nuclear Non Proliferation Treaty (NPT) it is entitled to enrich uranium for peaceful purposes.
Israel is widely believed to be the only nuclear armed-power in the Middle East.
