The Trump administration issued new economic sanctions against Iran on Tuesday over its ballistic missile program and alleged support of terrorist groups.
The new sanctions come a day after the Trump administration warned Iran that it was not following the terms of its nuclear agreement with world powers, according to a statement from U.S. State Department spokesperson Heather Nauert.
"The United States remains deeply concerned about Iran’s malignant activities across the Middle East which undermine regional stability, security, and prosperity," Nauert said. "Iran continues to support terrorist groups such as Hizballah, Hamas, and Palestinian Islamic Jihad that threaten Israel and stability in the Middle East."
The sanctions target "18 entities and individuals" that the department claims are "supporting Iran’s ballistic missile program."
The State Department also called on the Iranian government to release detained U.S. citizens.
"The Iranian regime also continues to detain U.S. citizens and other foreigners on fabricated national-security related charges," she said. "We call upon Iran to release U.S. citizens Baquer Namazi, Siamak Namazi, and Xiyue Wang, and all other unjustly detained U.S. citizens, so that they can be reunited with their families."
