Chapter 3: State Sponsors of Terrorism Overview

Bureau of Counterterrorism and Countering Violent Extremism



To designate a country as a State Sponsor of Terrorism, the Secretary of State must determine that the government of such country has repeatedly provided support for acts of international terrorism. Once a country is designated, it remains a State Sponsor of Terrorism until the designation is rescinded in accordance with statutory criteria. A wide range of sanctions are imposed as a result of a State Sponsor of Terrorism designation, including:

  • A ban on arms-related exports and sales;
  • Controls over exports of dual-use items, requiring 30-day Congressional notification for goods or services that could significantly enhance the terrorist-list country’s military capability or ability to support terrorism;
  • Prohibitions on economic assistance; and
  • Imposition of miscellaneous financial and other restrictions.

State Sponsor of Terrorism designations can be rescinded pursuant to two alternative paths.

One path requires that the President submit a report to Congress before the proposed rescission would take effect certifying that:

  • There has been a fundamental change in the leadership and policies of the government of the country concerned,
  • The government is not supporting acts of international terrorism, and
  • The government has provided assurances that it will not support acts of international terrorism in the future.

The other path requires that the President submit a report to Congress, at least 45 days before the proposed rescission would take effect, justifying the rescission and certifying that:

  • The government concerned has not provided any support for international terrorism during the preceding six-month period, and
  • The government concerned has provided assurances that that it will not support acts of international terrorism in the future.

This report provides a snapshot of events during 2015 relevant to countries designated as State Sponsors of Terrorism; it does not constitute a new announcement regarding such designations. More information on State Sponsor of Terrorism designations may be found at //


Designated as a State Sponsor of Terrorism in 1984, Iran continued its terrorist-related activity in 2015, including support for Hizballah, Palestinian terrorist groups in Gaza, and various groups in Iraq and throughout the Middle East. In 2015, Iran increased its assistance to Iraqi Shia terrorist groups, including Kata’ib Hizballah (KH), which is a U.S. designated Foreign Terrorist Organization, as part of an effort to fight the Islamic State of Iraq and the Levant (ISIL) in Iraq and bolster the Asad regime in Syria. Iran used the Islamic Revolutionary Guard Corps-Qods Force (IRGC-QF) to implement foreign policy goals, provide cover for intelligence operations, and create instability in the Middle East. The IRGC-QF is Iran’s primary mechanism for cultivating and supporting terrorists abroad.

Iran views the Asad regime in Syria as a crucial ally, a pillar in its “resistance” front together with sub-national groups aligned with Iran, and a key link to Hizballah, Iran’s primary beneficiary and terrorist partner. In addition to its ongoing support for Hizballah in Syria, Iran continued to provide arms, financing, training, and the facilitation of primarily Iraqi, Afghan, and Pakistani Shia fighters to support the Asad regime’s brutal crackdown that has resulted in the deaths of more than 250,000 people in Syria. Iran more openly acknowledged the deaths of Iranian personnel in Syria in 2015, including several senior commanders, and increased Iranian troop levels, while continuing to claim publicly that Iranian forces had only deployed in an advisory role.

In Iraq, Iranian combat forces employed rockets, artillery, and drones against ISIL. Iran also increased its arming and funding of Iraqi Shia terrorist groups in an effort to reverse ISIL gains in Iraq. Many of these groups, such as KH, have exacerbated sectarian tensions in Iraq and have committed serious human rights abuses against primarily Sunni civilians. The IRGC-QF, in concert with Hizballah, provided training outside of Iraq, as well as advisors inside Iraq for Shia militants in the construction and use of advanced weaponry. Similar to Hizballah fighters, many of these trained Shia militants have used these skills to fight for the Asad regime in Syria or against ISIL in Iraq.

Iran has also provided weapons, funding, and training to Shia militants in Bahrain. In 2015, the Government of Bahrain raided, interdicted, and rounded up numerous Iran-sponsored weapons caches, arms transfers, and militants. This includes the Bahraini government’s discovery of a bomb-making facility with 1.5 tons of high-grade explosives in September.

Iran has historically provided weapons, training, and funding to Hamas and other Palestinian terrorist groups, including Palestine Islamic Jihad and the Popular Front for the Liberation of Palestine-General Command. These Palestinian terrorist groups have been behind a number of deaths from attacks originating in Gaza and the West Bank. Although Hamas’s ties to Tehran have been strained due to the Syrian civil war, both sides took steps in 2015 to repair relations. Iran continued to declare its vocal support for Palestinian terrorist groups and its hostility to Israel in 2015. Supreme National Security Council Secretary Admiral Ali Shamkhani sought to frame a series of individual Palestinian attacks on Israeli security forces in the West Bank as a new “Intifada” in a speech on November 25.

Since the end of the 2006 Israeli-Hizballah conflict in 2006, Iran has also assisted in rearming Hizballah, in direct violation of UNSCR 1701. Iran has provided hundreds of millions of dollars in support of Hizballah in Lebanon and has trained thousands of its fighters at camps in Iran. These trained fighters have used these skills in direct support of the Asad regime in Syria and, to a lesser extent, in support of operations against ISIL in Iraq. They have also carried out isolated attacks along the Lebanese border with Israel.

Iran remained unwilling to bring to justice senior al-Qa’ida (AQ) members it continued to detain and refused to publicly identify the members in its custody. Iran previously allowed AQ facilitators to operate a core facilitation pipeline through Iran since at least 2009, enabling AQ to move funds and fighters to South Asia and Syria.


Sudan was designated as a State Sponsor of Terrorism in 1993 due to concerns about support to international terrorist groups to include the Abu Nidal Organization, Palestine Islamic Jihad, Hamas, and Hizballah.

In the mid-1990s, Sudan served as a meeting place, safe haven, and training hub for international terrorist groups, such as al-Qa’ida. Usama bin Laden was provided safe haven in Sudan for five years until he was expelled by the Sudanese government in 1996. Sudan’s support to al-Qa’ida has ceased but elements of al-Qa’ida and ISIL-linked terrorist groups remained active in Sudan in 2015. The United States and Sudan worked cooperatively in countering the threat posed by al-Qa’ida and ISIL in 2015, which included their use of transit and facilitation routes within the country.

In 2014, members of Hamas were allowed to raise funds, travel, and live in Sudan. However, in 2015 the use of Sudan by Palestinian designated terrorist groups appeared to have declined. The last known shipment was the Israeli-interdicted KLOS-C in 2014.

In June 2010, four Sudanese men sentenced to death for the killing of two U.S. Embassy staff members on January 1, 2008, escaped from Khartoum’s maximum security Kober prison. That same month of the escape, Sudanese authorities confirmed that they recaptured one of the four convicts, and a second escapee was reported killed in Somalia in May 2011. The recaptured murderer is being held in Kober Prison, and, as of December 2015, appeals of his pending death sentence were still ongoing. The whereabouts of the other two convicts were unknown at year’s end, although one is rumored to have been killed in Somalia in November 2015.


Designated in 1979 as a State Sponsor of Terrorism, the Asad regime continued its political support to a variety of terrorist groups affecting the stability of the region, even amid significant internal unrest. The regime continued to provide political and weapons support to Hizballah and continued to allow Iran to rearm the terrorist organization. The Asad regime’s relationship with Hizballah and Iran grew stronger in 2015 as the conflict in Syria continued. President Bashar al-Asad remained a staunch defender of Iran’s policies, while Iran has exhibited equally energetic support for Syrian regime efforts to defeat the Syrian opposition. Statements supporting terrorist groups, particularly Hizballah, were often in Syrian government speeches and press statements.

Over the past decade, the Syrian government has played an important role in the growth of terrorist networks in Syria through the Asad regime’s permissive attitude towards al-Qa’ida and other terrorist groups’ foreign fighter facilitation efforts during the Iraq conflict. Syria has served for years as a hub for foreign terrorist fighters; the Syrian government’s awareness and encouragement for many years of violent extremists’ transit through Syria to enter Iraq, for the purpose of fighting Coalition troops, is well documented. Those very networks were among the violent extremist elements, including ISIL, which terrorized the Syrian and Iraqi population in 2015 and – in addition to other terrorist organizations within Syria – continued to attract thousands of foreign terrorist fighters to Syria in 2015. This environment has also allowed ISIL to plot or encourage external attacks in Libya, France, Lebanon, Yemen, Saudi Arabia, Egypt, and the United States.

As part of a broader strategy during the year, the regime portrayed Syria itself as a victim of terrorism, characterizing all of the internal armed opponents as “terrorists.”

The Asad regime’s policies generate concern regarding terrorism financing. Industry experts reported that 60 percent of all business transactions are conducted in cash and that nearly 80 percent of all Syrians do not use formal banking services. Despite Syrian legislation that required money changers to be licensed by the end of 2007, many continued to operate illegally in Syria’s vast black market, estimated to be as large as Syria’s formal economy. Regional hawala networks (an informal value transfer system among money brokers operating outside traditional financial systems) remained intertwined with smuggling and trade-based money laundering, and were facilitated by notoriously corrupt customs and immigration officials. This raised concerns that some members of the Syrian government and the business elite were complicit in terrorist finance schemes conducted through these institutions.

The United States cannot certify that Syria is in compliance with its obligations under the Chemical Weapons Convention (CWC). The United States assesses that Syria has used chemical weapons systematically and repeatedly against the Syrian people every year since acceding the Convention, and is therefore in violation of its obligations under Article I of the CWC. In addition, the United States assesses that Syria did not declare all the elements of its chemical weapons program, required by Article III of the CWC and that Syria may retain chemical weapons as defined by the CWC. The process of verifying the accuracy and completeness of the Syrian declaration and the resolution of these matters is ongoing.
