The United States imposed sanctions on Iran in 1979 after students seized hostages at the US embassy in Tehran, effectively cutting off all US-Iranian diplomatic and economic relations. More recently, the US has pushed for UN sanctions, based on claims that that Iran's nuclear program hides nuclear weapons development. This page covers US and UN sanctions as well as the UN International Atomic Energy Agency's activities in Iran. In 1979, at the time of the Islamic revolution and the hostage crisis, the United States imposed broad economic sanctions against Iran. Since then, Washington has imposed various additional sanctions against Tehran, accusing the Iranian government of developing nuclear weapons and sponsoring or funding terrorism abroad. The sanctions block US-based oil companies from operating in Iran, giving the US a strong incentive to generalize the sanctions and block US firms' foreign competitors from operating there as well.
