The Trump administration is reinstating all sanctions on Iran that were lifted under the 2015 nuclear deal.
Secretary of State Mike Pompeo told reporters Friday the U.S. will reimpose sanctions on Iran's energy, shipbuilding, shipping and banking sectors starting Nov. 5.
Pompeo also said the U.S. will temporarily let eight "jurisdictions" continue to import Iranian oil after the sanctions go back into effect. Those jurisdictions will be named later.
President Donald Trump confirmed the move with a "Game of Thrones"-style tweet that read, "Sanctions are coming."
The U.S. has slowly been reinstating sanctions against Iran since Trump decided to pull out of the 2015 nuclear agreement earlier this year.
The first round of sanctions snapped back into place in August and affected Iran's trade in gold and other precious metals, its automotive sector and its purchases of U.S. dollars.
