The Trump administration on Tuesday unveiled new economic sanctions against Iran over its ballistic missile program and for contributing to regional tensions, one day after warning Tehran that it was not following the spirit of its nuclear agreement with world powers.

The U.S. Department of Treasury, in a statement, said it was targeting 16 entities and individuals for supporting what is said was “illicit Iranian actors or transnational criminal activity”.

Backers of military

Those sanctioned had backed Iran’s military or the Islamic Revolutionary Guard Corps by developing drones and military equipment, producing and maintaining boats, and procuring electronic components. Others has also “orchestrated the theft of U.S. and Western software programs”.

The U.S. State Department had also designated two Iranian organisations involved in Iran’s ballistic missile program, according to the Treasury Department.

“The United States remains deeply concerned about Iran’s malign activities across the Middle East which undermine regional stability, security, and prosperity,” the State Department said.
