Iran reiterates 'warning' to US after blacklisting of Revolutionary Guards

Iranian Foreign Minister Mohammad Javad Zarif said on Sunday he will send letters to the foreign ministers of all countries to notify them that the U.S. designation of the Revolutionary Guards as a terrorist organisation will have consequences.

Zarif was quoted by the state news agency IRNA as saying that he has also sent letters to United Nations Secretary-General Antonio Guterres and the United Nations Security Council to protest against "this illegal U.S. measure".
