"On July 28, the Iranian Revolutionary Guard reportedly released Osama bin Laden's 27 year-old son, Saad bin Laden, according to the German newspaper Die Welt. Saad had been held under house arrest in Iran, along with other al-Qaeda figures who were arrested in round-ups by Iranian intelligence services during the past two years. Iran did not previously confirm that they were holding top al-Qaeda figures—allegedly also including al-Qaeda strategist Sayf al-Adil—but it was widely speculated that they sought to exchange these prisoners with the United States for guarantees of U.S. non-aggression, which Washington rejected."
