WASHINGTON: United States has decided to reimpose economic sanctions against Iran from Tuesday.
In a statement, US President, Donald Trump said economic pressure will force Iran to agree to a new deal.
However, Iran's President Hassan Rouhani said the act was "psychological warfare".
The sanctions would target Iranian purchases of U.S. dollars, metals trading and other dealings, coal, industrial-related software and its auto sector.
Meanwhile, United Nations has expressed support for the Iran nuclear deal after Washington vowed to re-impose sanctions on Iran lifted under the deal.
UN spokesperson, Farhan Haq said UN Secretary-General Antonio Guterres continues to view the Joint Comprehensive Plan of Action as a diplomatic achievement.
