Netanyahu has been an outspoken opponent of Iran's landmark nuclear deal with major powers and was the leading supporter of United States President Donald Trump's decision to withdraw from it and reimpose crippling economic sanctions past year.
In an announcement previewed for days, Iran said Wednesday it would immediately stop implementing some restrictions under the 2015 deal - specifically the requirement that it restrict stocks of enriched uranium and heavy water.
Earlier on Wednesday, Iran announced it would no longer sell excess uranium and heavy water as provided under the JCPOA, citing last week's decision by the U.S. to end sanction waivers on these transactions.
Iran has denied ever seeking nuclear weapons, insisting its atomic program is for entirely peaceful purposes.
Following Washington's steps to curb Iranian energy exports, Tehran announced that it would cut back on some of its commitments under the nuclear deal - an accord that led to sanctions being lifted in 2015.
That Iran chose to keep its excess uranium and heavy water first, rather than abandon the accord in its entirety, indicates it still hopes to secure a deal.
Rouhani said the decision was a meant to resuscitate the agreement.
Trump says Mueller 'should not testify' before Congress
Apparently sensing that Democrats meant to turn the hearing into a circus, Barr simply skipped the hearing altogether. In one instance, the report said McGahn defied an order from the president to remove Mueller from the investigation.
Lavrov, who is meeting his counterpart Mohammad Javad Zarif in Moscow, said they will discuss the "unacceptable situation" compounded by the United States.
Prime Minister Theresa May's spokesperson said, "We are extremely concerned about this announcement and urge Iran to continue to meet its commitments under the deal and not to take escalatory steps".
Is the Iran nuclear deal dead? For now, Iran's stockpile of enriched uranium is still well below the deal's cap and heavy water is less sensitive. This includes the establishment of a special payments system to help worldwide companies who want to continue trading with Iran to bypass sanctions. All were signatories to the nuclear deal and continue to support it.
Rohani's remarks were made in an address to the nation aired by state television on May 8, the anniversary of President Donald Trump's decision to withdraw the United States from a landmark nuclear agreement.
Tehran said it would abandon even more limitations if the remaining parties to the agreement - Britain, China, France, Germany and Russian Federation - failed to start delivering on their commitments to sanctions relief within 60 days. This reconnected Iran's stagnating economy with world markets.
Geng's comments came after Washington moved to deploy an aircraft carrier and a bomber wing to confront unspecified threats from Tehran.
European backers of the deal, who oppose reinstating sanctions, have been trying to find ways to salvage it.
Iranian Foreign Minister Javad Zarif insisted that the decision to partially withdraw from certain provisions did not violate the agreement, and asserted it was provoked by USA actions toward Iran. Geranmayeh said Tehran is trying to convince Beijing to buck USA sanctions pressure and keep buying Iranian oil to keep its economy afloat but that China, now in the middle of a contentious trade war with the United States, has less room to thumb its nose at Washington than it did in the past.
