Iran
Since the inauguration of moderate President Mohammad Khatami in 1997, Iran has taken steps towards liberalization and made conciliatory gestures towards the United States—including public condemnations of terrorist attacks by Algerian and Egyptian groups. It remains, however, one of the most active state sponsors of international terrorism. It continues to support terrorist groups. In the trial of an Iranian and four Lebanese for the 1992 killing of Iranian Kurdish dissidents in a Berlin restaurant, a German court in 1997 found the Government of Iran to have implemented a policy of assassinating dissidents abroad. Iran conducted at least 13 such assassinations in 1997.

Iran
Iran remained the most active state sponsor of terrorism in 2003. Its Islamic Revolutionary Guard Corps and Ministry of Intelligence and Security were involved in the planning of and support for terrorist acts and continued to exhort a variety of groups that use terrorism to pursue their goals.
Iran’s record against al-Qaida remains mixed. After the fall of the Taliban regime in Afghanistan, some al-Qaida members fled to Iran where they have found virtual safehaven. Iranian officials have acknowledged that Tehran detained al-Qaida operatives during 2003, including senior members. Iran’s publicized presentation of a list to the United Nations of deportees, however, was accompanied by a refusal to publicly identify senior members in Iranian custody on the grounds of “security.” Iran has resisted calls to transfer custody of its al-Qaida detainees to their countries of origin or third countries for further interrogation and trial.
During 2003, Iran maintained a high-profile role in encouraging anti-Israeli activity, both rhetorically and operationally. Supreme Leader Khamenei praised Palestinian resistance operations, and President Khatami reiterated Iran’s support for the “wronged people of Palestine” and their struggles. Matching this rhetoric with action, Iran provided Lebanese Hizballah and Palestinian rejectionist groups -- notably HAMAS, the Palestine Islamic Jihad, and the Popular Front for the Liberation of Palestine–General Command -- with funding, safehaven, training, and weapons. Iran hosted a conference in August 2003 on the Palestinian intifadah, at which an Iranian official suggested that the continued success of the Palestinian resistance depended on suicide operations.
Iran pursued a variety of policies in Iraq aimed at securing Tehran’s perceived interests there, some of which ran counter to those of the Coalition. Iran has indicated support for the Iraqi Governing Council and promised to help Iraqi reconstruction.
Shortly after the fall of Saddam Hussein, individuals with ties to the Revolutionary Guard may have attempted to infiltrate southern Iraq, and elements of the Iranian Government have helped members of Ansar al-Islam transit and find safehaven in Iran. In a Friday Prayers sermon in Tehran in May, Guardian Council member Ayatollah Ahmad Jannati publicly encouraged Iraqis to follow the Palestinian model and participate in suicide operations against Coalition forces.
Iran is a party to five of the 12 international conventions and protocols relating to terrorism
