Allegations of Iranian state terrorism

Since the Iranian Revolution in 1979, the government of Iran has been accused by members of the international community of funding, providing equipment, weapons, training and giving sanctuary to terrorists.

The United States State Department describes Iran as an “active state sponsor of terrorism.” Former US Secretary of State Condoleezza Rice elaborated stating, "Iran has been the country that has been in many ways a kind of central banker for terrorism in important regions like Lebanon through Hezbollah in the Middle East, in the Palestinian Territories, and we have deep concerns about what Iran is doing in the south of Iraq." Iranian sponsorship of terror is significant, but not dominant. According to the Global Terrorism Database, the majority of deaths, more than 94% attributed to Islamic terrorism since 2001, were perpetrated by Sunni jihadists of the Islamic State, al-Qaeda and others.. Iran supports Shia militias and militant groups as well as some allied Sunni militan groups that engage in insurgencies or terrorist acts, including the Iraqi Shia in Iraq, Hezbollah in Lebanon, Islamic Jihad (PIJ), the Popular Front for the Liberation of Palestine-General Command (PFLP-GC), and, to a lesser extent, Hamas in Gaza and the Houthis in Yemen, among others.
