"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. In addition, the IRGC was increasingly involved in supplying lethal assistance to Iraqi militant groups, which destabilizes Iraq.
Iran continues to be unwilling to bring to justice senior al-Qaida members it detained in 2003. Iran has refused to identify publicly these senior members in its custody on "security grounds." Iran has also resisted numerous calls to transfer custody of its al-Qaida detainees to their countries of origin or to third countries for interrogation and/or trial.
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 pursued a variety of policies in Iraq, some of which appeared to be inconsistent with its stated objectives regarding stability in Iraq and with the objectives of the Iraqi Transitional Government and the Multi-national Forces in Iraq. Senior Iraqi officials have publicly expressed concern over Iranian interference in Iraq, and there were reports that Iran provided funding, safe passage, and arms to insurgent elements."
