As President Trump wrapped up his first foreign trip on Friday, Iranian leaders made another defiant declaration in the war of words unfolding between Tehran and Washington.

According to a senior Revolutionary Guard commander who spoke to the semi-official Fars news agency, the regime has apparently built a third underground missile factory despite sanction by both the U.S. and the United Nations.

The announcement flies in the face of a series of statements and sanctions designed to curtail this exact kind of activity. A 2015 U.N.
