In a speech in Tehran, Iranian Supreme Leader Ali Khamenei called on the regime leaders and the Iranian people to demonstrate unity in light of the sensitive situation in the region. Khamenei said that the regime's enemies had exploited for their own propaganda his attempts to prevent Ahmadinejad's dismissal of intelligence minister Heidar Moslehi, but that he would continue to intervene in the affairs of the Iranian government as long as he felt that the regime was in danger.
