US sanctions Iran's metal sectors as tensions heighten

             By Michael Hernandez</p>  <p>WASHINGTON (AA) - U.S. President Donald Trump imposed sanctions on Iran's iron, steel, aluminum, and copper sectors Wednesday as tensions between the rivals escalates. </p>  <p>The penalties affect what Trump called the Iranian government's &quot;largest non-petroleum-related sources of export revenue&quot; one year after he pulled the U.S. out of a landmark nuclear accord that placed unprecedented curbs on Tehran's nuclear program. </p>  <p>Trump and his senior officials have embarked upon a wide-ranging campaign to ramp up pressure on the Iranian government in the time since, including reimposing sanctions on Iran's oil sector that were lifted as part of the 2015 agreement. </p>  <p>&quot;Tehran can expect further actions unless it fundamentally alters its conduct,&quot; the president said in a statement. &quot;Since our exit from the Iran deal, which is broken beyond repair, the United States has put forward 12 conditions that offer the basis of a comprehensive agreement with Iran.&quot;
