TEHRAN: Iran will "resolutely" abandon more commitments under a 2015 nuclear deal with world powers on July 7, Fars News Agency reported on Tuesday quoting a "note" from a top security official.
Tehran had announced on May 8 that it was suspending two of its 2015 pledges and gave Europe, China and Russia a two-month ultimatum to help Iran circumvent US sanctions and sell its oil or it would abandon two more commitments.
In response, France said that Iran would be making a "serious mistake" in violating the nuclear deal, which the US pulled out of last year.
Iran also said on Tuesday that a US decision to impose sanctions on the country’s supreme leader and other top officials permanently closed the path to diplomacy between Tehran and Washington.
“Imposing useless sanctions on Iran’s Supreme Leader (Ayatollah Ali Khamenei) and the commander of Iran’s diplomacy (Foreign Minister Mohammad Javad Zarif) is the permanent closure of the path of diplomacy,” Foreign Ministry spokesman Abbas Mousavi said in a tweet.
“Trump’s desperate administration is destroying the established international mechanisms for maintaining world peace and security.”
US President Donald Trump earlier signed an executive order that would impose fresh sanctions on Iran, amid increased tensions between the long-time foes.
Trump initially told reporters the sanctions, which will target Iranian Supreme Leader Ayatollah Ali Khamenei and his office, were in response to Tehran's downing of a US drone last week. Tehran has said the drone was flying in its airspace, which Washington has denied.
Later, Trump said the sanctions would have been imposed regardless of the incident over the drone.
The US will also blacklist Iran's Foreign Minister Mohammad Javad Zarif and block "billions" more in Iranian assets as part of expanded sanctions, US Treasury Secretary Steven Mnuchin said Monday.
Mnuchin told reporters Zarif would be added to an economic sanctions list "later this week," adding that eight top military commanders from Iran's Revolutionary Guards have now also been blacklisted.
The US has also blamed Iran for attacks earlier this month on two oil tankers at the entrance of the Gulf of Oman. Iran, in turn, has denied that it is to blame.
Russia on Tuesday accused Washington of being reckless with the new sanctions on Iran, saying Moscow "stood in solidarity" with Tehran.
"US authorities should think hard about where this reckless course of action can lead," the foreign ministry said in a statement. "It is capable of not only destabilising the Middle East but undermining the entire system of international security.
"There is an impression that Washington is 'burning bridges,' Russia stands in complete solidarity with the friendly people of Iran and its government," the Russian foreign ministry added.
Washington has repeatedly imposed sanctions on Tehran since last year, after withdrawing from the 2015 Iran nuclear deal to curb Iran's nuclear program in exchange for easing of sanctions. Trump’s administration has said the deal struck under his predecessor President Barack Obama did not do enough.
Trump has said he would be open to talks with Iranian leaders, but Tehran has rejected such an offer unless Washington drops the sanctions.
The Trump administration wants to force Tehran to open talks on its nuclear and missile programmes and its activities in the region.
The US also accuses Iran of encouraging allies in Yemen to attack Saudi targets. In a joint statement on Monday, the US, Ƶ, the UAE and UK expressed concern over Middle East tensions and the dangers posed by Iranian "destabilizing activity" to peace and security in Yemen and the region.
