It suggested in its Tuesday edition that Iran may install advanced centrifuges at its Natanz facility and begin enrichment at its Fordo facility, activities prohibited under the nuclear deal.
"We call on the Iranian regime to cease all provocation", the acting Pentagon chief noted, adding "we will hold the Iranian regime accountable for any attack on USA forces or our interests". "In that case, the restrictions under the JCPOA may be reviewed", Zarif said.
"Being aware of the U.S. policies, the Islamic Republic of Iran has faced the issue with strategic patience", a statement on Irna said. Iranian Foreign Minister Mohammad Javad Zarif was to meet Wednesday in Moscow with his Russian counterpart.
U.S. President Donald Trump pulled out of the deal past year, and subsequently reimposed tough sanctions on Iran, including on its lifeblood oil exports with the stated intent of reducing them to zero and starving Iran's economy.
There was no immediate response from the US.
He said: "This surgery is to save the deal, not destroy it".
Iran's hard-line Javan newspaper, associated with the Revolutionary Guard, said Wednesday would "ignite the matchstick for burning the deal".
Iran reached the deal with world powers in 2015 after years of negotiations, including secret talks between Iran and President Barack Obama's administration in Oman.
"To my peers, you know full well the role Iran plays in the region, but the cost of security is too high".
Washington's European allies say Trump's repudiation of the deal hurts the pragmatic wing of Iran's leadership and plays into the hands of hardliners. He added, "We will continue enrichment whether you want to purchase it or not", referring to the arrangement in which Iran exports low-enriched uranium in exchange for natural uranium.
Iran will reportedly soon announce reciprocal measures in the face of the Donald Trump administration's revoking of sanctions waivers allowing nuclear cooperation with Iran.
Iranian state television says letters outlining the Islamic Republic's partial withdrawal from its 2015 nuclear deal with world powers have been delivered to ambassadors. Rouhani said Iran wanted to negotiate new terms with remaining partners in the deal, but acknowledged that the situation was dire.
In 2018, all the other signatories - Russia, China, Germany, France, the United Kingdom, and the European Union - refused to follow the U.S. example and confirmed their commitment to the accord, trying to save the deal with the Islamic Republic.
Under the 2015 accord, Iran restricted the capacity of its uranium enrichment program in exchange for a lifting of most worldwide sanctions.
Rouhani also said that if the 60 days pass without action, Iran will halt a Chinese-led effort to redesign its Arak heavy water nuclear reactor.
Tehran has lost patience with Europe's efforts to create a new viable financial mechanism that would allow European firms to continue trading items such as medicines and humanitarian goods with Iran and circumvent U.S. secondary sanctions.
