In a session this morning, 240 Iranian lawmakers voted for the bill to confront "America's terrorist and adventurous actions" in the region.
On August 2, US President Donald Trump signed into law a bill by Congress that imposes new sanctions against Russia, Iran and North Korea.
Chants of "Death to America" broke out as the bill was passed, according to the country's state broadcaster IRIB.
The bill would allocate about $260 million each to Iran's ballistic-missile program and the Quds Force, the external branch of the IRGC that is said to be active in Syria and Iraq.
He further said American officials should be aware that the legislation was just the first step against anti-Iran measures.
Deputy Foreign Minister Abbas Araqchi, who is the head of an Iranian commission tasked with monitoring the agreement's implementation, told MPs that the government backed the bill which he described "very strong".
Devising the Sunday motion, the Parliament took great care not to violate the nuclear accord and provide excuses for opposing sides, spokesman for Parliament's Committee on National Security and Foreign Policy Hossein Naqavi Hosseini said.
With the newly passed funding bill, Iran's parliament offered a rebuke of the US sanctions.
Tensions between Tehran and Washington have grown since President Trump took office.
Deputy Foreign Minister for Legal and International Affairs Seyyed Abbas Araqchi said the government fully supports the new law passed by the parliament against the U.S. terrorist and adventurous measures in the region, describing it as a "wise" and "appropriate" move against Washington's enmities towards Iran.
Iran denies developing ballistic missiles created to carry nuclear weapons in violation of the agreement and has accused the United States of breaking its word by imposing fresh sanctions.
