State Sponsors of Terrorism
Iran
Iran remained the most active state sponsor of terrorism. Its Islamic Revolutionary Guard Corps (IRGC) and Ministry of Intelligence and Security (MOIS) were directly involved in the planning and support of terrorist acts and continued to exhort a variety of groups, especially Palestinian groups with leadership cadres in Syria and Lebanese Hizballah, to use terrorism in pursuit of their goals.
Iran maintained a high-profile role in encouraging anti-Israeli terrorist activity, rhetorically, operationally, and financially. Supreme Leader Khamenei and President Ahmadi-Nejad praised Palestinian terrorist operations, and Iran provided Lebanese Hizballah and Palestinian terrorist groups - notably HAMAS, Palestinian Islamic Jihad, the al-Aqsa Martyrs Brigades, and the Popular Front for the Liberation of Palestine-General Command - with extensive funding, training, and weapons.
Iran continued to play a destabilizing role in Iraq, which appeared to be inconsistent with its stated objectives regarding stability in Iraq. Iran provided guidance and training to select Iraqi Shia political groups, and weapons and training to Shia militant groups to enable anti-Coalition attacks. Iranian government forces have been responsible for at least some of the increasing lethality of anti-Coalition attacks by providing Shia militants with the capability to build IEDs with explosively formed projectiles similar to those developed by Iran and Lebanese Hizballah. The Iranian Revolutionary Guard was linked to armor-piercing explosives that resulted in the deaths of Coalition Forces. The Revolutionary Guard, along with Lebanese Hizballah, implemented training programs for Iraqi militants in the construction and use of sophisticated IED technology. These individuals then passed on this training to additional militants in Iraq.
Iran remained unwilling to bring to justice senior AQ members it detained in 2003, and it has refused to publicly identify these senior members in its custody. Iran has repeatedly resisted numerous calls to transfer custody of its AQ detainees to their countries of origin or third countries for interrogation or trial. Iran also continued to fail to control the activities of some al-Qaida members who fled to Iran following the fall of the Taliban regime in Afghanistan.
