Iran's President Mahmoud Ahmadinejad has issued a tough warning to any country considering an attack on Iran.It's starting to sound as though ol' Mahmoud has an invisible friend.
He said Iran's forces were just for defence, but that anybody who attacked would experience nothing but regret. On display at the parade was Iran's latest military hardware, including new long-range missiles and Saegheh fighter jets.
According to the Associated Press news agency some of the lorries carrying Iranian missiles bore anti-US and anti-Israeli slogans.
The BBC's Jon Leyne in Tehran says Mr Ahmadinejad believes he is winning the battle for world opinion - a fight he is now taking to the UN General Assembly in New York.
