Donald Trump tweeted that Iran has been formally warned by the US for firing a ballistic missile over the weekend. Trump repeatedly criticized the Iranian nuclear agreement during the course of his campaign, saying that he would "tear up" the deal if he became president.

Trump wrote that "Iran was on its last legs and ready to collapse until the U.S. came along and gave it a life-line in the form of the Iran Deal: $150 billion.

"Iran has been formally PUT ON NOTICE for firing a ballistic missile. Should have been thankful for the terrible deal the U.S. made with them!" (Emphasis Trump's)

According to a 2015 U.N. resolution endorsing the Iranian deal, Iran is still called upon to refrain for up to eight years from work on ballistic missiles designed to deliver nuclear weapons.
