The United States has imposed a new anti-Iran measure, extending the scope of metals sanctions against Tehran. 

Iran Press/America: "Today, I expanded the scope of Iran metals sanctions targeting Iran’s nuclear, military, and ballistic missile programs," US Secretary of State Mike Pompeo said in a tweet on Thursday.

"Those who knowingly transfer such materials to Iran are now sanctionable," he added.

The materials he said he had determined are used in connection with Iran’s nuclear, military or ballistic missile programs included aluminum powder with purity above 98%.

The 22 specific materials include multiple forms of aluminum, steel, among others.
