IRAN wheeled out scores of gun-toting soldiers and weapons at its annual army day parade today before issuing another warped threat against Israel.
President Raisi snarled during the sabre-rattling ceremony that even the "smallest action" by Israel would spark a "fierce" and "painful" response.
Speaking at the staged show of strength, the president Ebrahim Raisi delivered Iran's latest warning after days of the countries hurling tit-for-tat threats back and forth.
He raged: "The smallest action against Iran's interests will definitely be met with a fierce, widespread and painful response against all its perpetrators."
The parade this year was moved from the usual highway snaking around capital Tehran's south to a secure barracks north of the city.
Iranian State TV also did not broadcast the ceremony live as with previous years.

Ali Ansari, a professor of Iranian studies and a member of think tank RUSI, told The Sun: "My sense is the Israelis will directly hit Iranian soil.
