Semi-official media in Iran are quoting the country’s nuclear agency spokesperson as saying Tehran is now enriching uranium to 4.5 per cent.

The ISNA and Fars news agencies each quoted Behrouz Kamalvandi, the spokesperson of the Atomic Energy Organization of Iran. 

Kamalvandi told the agencies this decision met the needs that Iran has now. 

His comments come a day after Iran announced it would break the 3.67 per cent limit imposed by its 2015 nuclear deal with world powers. It earlier broke a limit put on its stockpile of low-enriched uranium.

Iran said on Sunday it would shortly boost uranium enrichment above the cap, prompting a warning from U.S. President Donald Trump, who wants the pact renegotiated, that Tehran “better be careful.” 

Kamalvandi said Iran may enrich at even higher levels, according to the IRIB news agency. 

“Twenty per cent is not needed now, but if we want, we will produce it,” Kamalvandi was quoted as saying, noting that options for enriching at higher levels had been discussed with the Supreme National Security Council.

Iran also said the last chance for saving its nuclear deal with world powers will pass after a 60-day deadline.

Iranian Foreign Ministry spokesperson Abbas Mousavi told reporters Monday that Iran won’t offer any further “deadlines” to save the deal by September.

A day earlier, Iranian officials said the country would take further steps toward the “reduction” of its compliance with the accord after the deadline.

Mousavi said Iran is still open to negotiations with its European partners and expressed the hope they would “take steps forward” toward implementing their commitments.

Iran is pressuring European partners to find a way around U.S. sanctions and deliver the deal’s promised economic relief. The U.S. unilaterally withdrew a year ago.
