Trump Administration Iran Sanctions Take Effect |

The Trump administration's tough new sanctions on Iran have taken effect, but eight major importers of Iranian oil are being spared from immediate penalties.

The sanctions target Iran's energy, financial and shipping sectors and are aimed at crippling the country's economy following President Donald Trump's withdrawal from the 2015 nuclear deal. The measures that came into effect on Monday restore all the sanctions that had been lifted under the accord that gave Iran billions of dollars in sanctions relief in exchange for curbs on its nuclear program.

But as the administration seeks to cut off Iran's oil revenue it will allow some of its closest allies and rival China to continue to purchase Iranian oil as long as they work to reduce imports to zero.

Besides China, Greece, India, Italy, Turkey, South Korea, Taiwan and Japan get U.S. sanctions waivers for Iran oil imports.

On Friday, Trump tweeted a photo of himself with the words "Sanctions are Coming" Nov. 5.

It's the second batch of penalties that the administration has reimposed since Trump, a former reality TV star, withdrew from the landmark deal in May.

The sanctions cover Iran's shipping, financial and energy sectors.

Secretary of State Mike Pompeo and Treasury Secretary Stephen Mnuchin made the announcement Friday. They say sanctions will remain until Iran meets demands that include ending support for terrorism, ending military engagement in Syria and completely halting its nuclear and ballistic missile development.

In response to President Trump's tweet, HBO replied with this tweet - "How do you say trademark misuse in Dothraki?"
