"There are other countries in the region with such programs; we must look at it as a whole as it is hardly justified to mix nuclear affairs with defense affairs and human rights and put the issue on the agenda that Iran should stop taking certain steps in the region," Lavrov said.
"To my mind, a frankly discriminatory, biased and unjustifiably captious approach can be seen behind these US actions," the Russian foreign minister added.
Lavrov pointed to Iran nuclear deal officially known as Joint Comprehensive Plan of Action (JCPOA), and said, "This agreement is effective."
US President Donald Trump, who had said his administration would decertify the 2015 nuclear deal with Iran, decided on Jan 12 to extend the sanctions waiver to the country for the third time as a part of the JCPOA.
He claimed that this is the "last time" that he certified the JCPOA unless the amendments that he had mentioned earlier be included to the landmark nuclear deal.
Since Trump announced his decision on Iran deal, many European and American officials have expressed support for the deal.
“We remain committed to the continued full and effective implementation of the Joint Comprehensive Plan of Action,” EU spokesperson earlier said taking note of US President Donald Trump’s recent statement on Iran deal.
