FNA- Iranian Foreign Ministry Spokesman Bahram Qassemi described the US treasury sanctions on more individuals in Iran as an "unwise" move, and said the move is mostly aimed at leaving psychological pressure on Tehran.

"The US sanctions on more individuals are an unwise move which continues based on the wrong policies of the past and shows that the US administration, specially the new one, has not yet come to realize the regional and global realities and still see itself in the past decades," Qassemi said on Wednesday.

Noting that the new US sanctions against Iran are mostly political, he said, "They have been imposed to exert psychological pressure on Iran."

Qassemi warned that Iran will give a decisive response to the US defiance of the 2015 nuclear deal in due time.

In relevant remarks on Tuesday, Iranian Deputy Foreign Minister Majid Takht Ravanchi underlined that Tehran is resolved to save the nuclear deal it has struck with the Group 5+1 (the US, Russia, China, France and Britain plus Germany) in Vienna in July 2015, but meantime the country is preparing for every scenario.

"Tehran will not leave the nuclear agreement first, but preparing itself for every scenario," Takht Ravanchi said.

Iran and the Group 5+1 signed the nuclear agreement on July 14, 2015 and started implementing it on January 16, 2016.

Under the JCPOA, Iran undertook to put limitations on its nuclear program in exchange for the removal of nuclear-related sanctions imposed against Tehran.

The IAEA has consistently verified Iran�s adherence to the terms of the JCPOA since the deal started being implemented.

However, on October 13, 2017 US President Donald Trump said his administration had decided to decertify Iran's compliance with the JCPOA, but had not challenged Iran's compliance with the deal at the international level. The US president also ordered the Treasury Department to impose new sanctions against Iran's Islamic Revolution Guards Corps (IRGC).
