"Secretary of State (Mike. - RT ) Pompeo extended (action. - RT ) restrictions on the nuclear program of the Iranian regime," - said a TASS diplomat.

The State Department expressed confidence that Tehran is using a nuclear program "to blackmail the international community and threaten regional security."

Ortagus stressed that the United States is ready to "use the full range of its diplomatic and economic means to limit Iran’s nuclear activities."

Earlier, the US Treasury announced the introduction of sanctions against Iranian Foreign Minister Mohammad Javad Zarif.

The White House later stressed that they would continue to exert maximum sanctions pressure on Iran until Tehran abandons its policy.
