On 15 June, Mousavi rallied, with anywhere from hundreds of thousands to three million, of his supporters in Tehran, despite being warned by state officials that any such rally would be illegal. The demonstration, the largest in the Islamic Republic of Iran's 30-year history, was Mousavi's first public appearance after the election. Protests focused around Azadi Tower, around which lines of people stretched for more than nine kilometers met. Gunshots were reported to have been fired at the rally, where Mousavi had spoken to his supporters saying, "The vote of the people is more important than Mousavi or any other person." All three opposition candidates appeared.
