U.S. will do everything it can to enforce U.N. sanctions on Iran -Pompeo

Pompeo told reporters at the United Nations it would be an "enormous mistake" not to extend the arms embargo on Iran, adding the U.S. will never allow Iran to freely buy and sell conventional weapons such as tanks.

His remarks came after the United States moved to restore all U.N. sanctions on Iran on Thursday, arguing Tehran was in violation of a nuclear deal it struck with world powers in 2015 even though Washington itself abandoned that agreement two years ago.
