The United States announced new sanctions against Iran Tuesday over its ballistic missile program and what it called Tehran's support for terrorist groups in the Middle East.

The sanctions announced by the State Department target 18 individuals or entities described as supporting Iran's ballistic missile program or the elite Republican Guard.

The announcement came a day after the United States certified that Iran was complying with the landmark nuclear deal signed two years ago with the United States and other world powers, but also warned it was preparing new sanctions.
