Tehran: President Hassan Rouhani said Tuesday that Iran would resume uranium enrichment at an underground plant south of Tehran in its latest step back from a troubled 2015 agreement with major powers.
The suspension of all enrichment at the Fordow plant in the mountains near the Shiite holy city of Qom was one of the restrictions on its nuclear activities that Iran accepted in return for the lifting of international sanctions.
But Washington's abandonment of the deal in May last year followed by its reimposition of crippling sanctions prompted Iran to begin a phased suspension of its own commitments in May this year.
Rouhani recalled that under the terms of the agreement Iran had retained more than 1,000 centrifuges at the plant which had been running empty since it went into effect.
"Starting from tomorrow (Wednesday), we will begin injecting (uranium hexafluoride) gas at Fordo," Rouhani said in a speech broadcast by state television.
Meanwhile, Russia on Tuesday expressed concern about Iran's decision to resume uranium enrichment at an underground plant south of Tehran, in its latest step back from an agreement with major powers.
