Washington: The United States vowed to remain "relentless" in pressuring Iran to deter its missile program after the country unveiled a new ballistic weapon days after testing a cruise missile.
Iran's Revolutionary Guards unveiled a new ballistic missile with a range of 1,000 kilometres (620 miles), their official news agency Sepah News reported.
The move was the latest show of military might by the country as it celebrates the 40th anniversary of the Islamic Revolution at a time of heightened tensions with the United States.
"Iran's blatant disregard for international norms must be addressed," State Department deputy spokesman Robert Palladino said in a statement.
"We must bring back tougher international restrictions to deter Iran's missile programme," he added.
"The United States will continue to be relentless in building support around the world to confront the Iranian regime's reckless ballistic missile activity, and we will continue to impose sufficient pressure on the regime so that it changes its malign behavior - including by fully implementing all of our sanctions."
"Iran's latest missile launch again proves the Iran deal is doing nothing to stop Iran's missile programme," Secretary of State Mike Pompeo tweeted.
Iran and the other signatories have stuck by the 2015 nuclear agreement, although some European governments have demanded an addition to address Tehran's ballistic missile program and its intervention in regional conflicts.
Meanwhile, UN Security Council Resolution 2231 - adopted just after the nuclear deal - calls on Iran "not to undertake any activity related to ballistic missiles designed to be capable of delivering nuclear weapons".
Tehran insists that its missile development program is "purely defensive" and compliant with the resolution.
