The head of Iran's atomic agency has said that 1,044 centrifuges were active at the Fordow uranium enrichment plant, in line with steps to reduce its commitments to the nuclear deal.
The suspension of all enrichment at the underground facility was one of the restrictions on Iran's nuclear activities that it accepted in return for the lifting of international sanctions in the 2015 landmark accord.
Tehran first announced the resumption of enrichment at Fordow last November, the fourth phase of its push since May 2019 to progressively suspend commitments to the deal.
It was in retaliation to Washington's abandonment of the accord in May 2018 followed by its unilateral reimposition of sanctions.
"Currently 1,044 centrifuges are enriching at Fordow," Ali Akbar Salehi, the head of Iran's atomic agency, told the Iranian parliament's news agency ICANA, according to Agence France Presse.
"We were committed in the JCPOA that these 1,044 machines do not carry out enrichment, but it is being done per dropped commitments as much as needed and we will stockpile the enriched material, too," he added, referring to the accord's official name, the Joint Comprehensive Plan of Action.
Iran's other walk-back steps included exceeding the accord's restrictions on enriched uranium reserves and enrichment level, development of advanced centrifuges, and foregoing a limit on its number of centrifuges.
