On Friday, Araqchi told media in Vienna that the 2015 Iran nuclear deal should be fully implemented in all aspects, and that Tehran is not satisfied with the United States because of the sanctions imposed on Iran over its ballistic missile program.

During his presidential campaign, US President Donald Trump quarreled with the Iranian nuclear deal, achieved during the administration of his predecessor, Barack Obama. The Trump administration is now reconsidering US policy on Iran.

Iran and six world powers, namely Britain, China, France, Germany, Russia and the United States, reached an agreement on the Iranian nuclear issue in July 2015, which put Tehran on the path of sanctions relief but with more strict limits on its nuclear program.

Besides, Iranian Foreign Ministry Spokesman Bahram Qasemi said Wednesday that the US Congress bill against Iran will jeopardize the implementation of the JCPOA.

The US fresh sanctions against Iran is "an illegal and insulting act," Qasemi said, adding that the United States should not overlook its obligation vis-a-vis the nuclear deal.

Moreover, Deputy Chief of Staff of the Iranian Armed Forces Brigadier General Massoud Jazayeri condemned the US congressional decisions and warned Washington to be more cautious about its approaches toward the Islamic Republic, Tasnim news agency reported.

Jazayeri said that Iranian armed forces, heedless of US pressures, "will push their ways to reach the peaks of progress and will make it (the United States) regret its mischievous acts."
