President Donald Trump said the renewed U.S. campaign against Iran would not continue for too long after the biggest exchange of fire between Tehran and Washington since July. Trump said Iran was building a rocket capable of dropping mines and that the United States had destroyed it. He also said U.S. strikes targeted Iranian efforts to restore radar and missile systems. Trump said the attacks eliminated newly built defensive and offensive equipment along the Strait of Hormuz, and that the United States was prepared to launch another attack whenever it chose.
