Iran's president warned European partners on Wednesday that Tehran will increase its enrichment of uranium to any amount it wants, starting on Sunday.
The comments by President Hassan Rouhani come as tensions remain high between Iran and the US over the deal, which President Donald Trump pulled America from over a year ago, the Associated Press (AP) Reported.
According to authorities, Iran did break through a limit placed on its stockpile of low-enriched uranium.
An increasing stockpile and higher enrichment closes the estimated one-year window Iran would need to produce enough material for a nuclear bomb, something Iran denies it wants but the nuclear deal sought to prevent.
Speaking at a Cabinet meeting in Tehran, Rouhani's comments hinted that Europe has yet to offer Iran anything to alleviate the consequences of the renewed US sanctions targeting its oil industry and top officials.
Iran's nuclear deal currently bars it from enriching uranium above 3.67%, which is enough for nuclear power plants but far below the 90% needed for weapon-grade levels, according to AP.
"In any amount that we want, any amount that is required, we will take over 3.67," Rouhani stressed.
