Overview of State-Sponsored Terrorism
Iran
Iran remained the most active state sponsor of terrorism in 2002. 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 has been mixed. While it has detained and turned over to foreign governments a number of al-Qaida members, other al-Qaida members have found virtual safehaven there and may even be receiving protection from elements of the Iranian Government. Iran's long, rugged borders are difficult to monitor, and the large number of Afghan refugees in Iran complicates efforts to locate and apprehend extremists. Nevertheless, it is unlikely that al-Qaida elements could escape the attention of Iran’s formidable security services.
During 2002, Iran maintained a high-profile role in encouraging anti-Israeli activity, both rhetorically and operationally. Supreme Leader Khamenei referred to Israel as a “cancerous tumor,” a sentiment echoed by other Iranian leaders in speeches and sermons. 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. Tehran also encouraged Hizballah and the Palestinian rejectionist groups to coordinate their planning and to escalate their terrorist activities against Israel.
Iran also provided support to extremist groups in Central Asia, Afghanistan, and Iraq with ties to al-Qaida, though less than that provided to the groups opposed to Israel.
In 2002, Iran became party to the 1988 Protocol on the Suppression of Unlawful Acts of Violence at Airports Serving International Civil Aviation. It is party to five of the 12 international conventions and protocols relating to terrorism.
