Iran Foreign Ministry spokesman Esmaeil Baqaei says the parliament is working on legislation to abandon the Nuclear Non-Proliferation Treaty (NPT).
He added, however, that Tehran remains opposed to developing weapons of mass destruction, Al Jazeera and Jerusalem Post reported.
The 190-member NPT, which was signed in 1968 and came into effect in 1970, bans signatories other than the United States, Russia, China, Britain and France from acquiring nuclear weapons – in return for allowing them to pursue peaceful nuclear programmes for power generation, overseen by the UN.
Iran has gradually stepped back from its obligations under the accord after US President Donald Trump quit the Iranian nuclear deal in 2018, and reimposed crushing sanctions that have severely harmed the Iranian economy.
