"Iran’s 4th step in reducing its commitments under the JCPOA by injecting gas to 1044 centrifuges begins today," Rouhani announced.
"Thanks to US policy and its allies, Fordow will soon be back to full operation," he added.
In his Wednesday tweet, Rouhani referred back to his earlier tweet from May 8, when he wrote "Starting today, Iran does not keep its enriched uranium and produced heavy water limited. The EU/E3+2 will face Iran's further actions if they can not fulfill their obligations within the next 60 days and secure Iran's interests. Win-Win conditions will be accepted."
Iran is making final preparations for injecting gas into centrifuges at Fordow enrichment facility as part of a fourth step in suspending its commitments under the 2015 nuclear deal in reciprocation for Washington’s pullout and Europe’s failure to meet its end of the bargain.
The gas injection began early Wednesday with the transfer of a 2,800-kilogram cylinder containing 2,000 kilograms of UF6 (uranium hexafluoride) from Natanz nuclear facility to Fordow - near the city of Qom, where 1,044 centrifuges are installed.
The deal allowed the first-generation IR-1 centrifuges at Fordow to spin without uranium gas.
The process is taking place under the supervision of inspectors from the International Atomic Energy Agency (IAEA). The UN nuclear watchdog is tasked with monitoring the technical aspects in the implementation of the Joint Comprehensive Plan of Action (JCPOA).
An IAEA spokesman confirmed that UN inspectors are on the ground in Iran and will report back on relevant activities.
The Islamic Republic says the suspension of its commitments is not a violation of the JCPOA but is based on Articles 26 and 36 of the agreement itself.
The fate of the Iran deal has been in doubt since May 2018, when the US abruptly abandoned the deal and reinstated the anti-Iran sanctions that it had lifted as part of the JCPOA.
Tehran says the European cosignatories — Britain, Germany and France — have so far failed to uphold their commitments.They have expressed vocal support for the deal, but failed to provide meaningful economic incentives as required under the nuclear agreement.
