Iranian President Hassan Rouhani reiterated that the Islamic Republic had no intention of making a nuclear bomb and called on world powers to honour the deal.
"Don't worry about Iran. We have always remained committed to our obligations," Rouhani said in a televised cabinet meeting on Thursday.
"Even today, if we wish, we can enrich uranium at 90% purity. But we are not seeking a nuclear bomb ... If others return to full compliance with the deal ... we will stop 60% and 20% enrichment."
He said Tehran would then return to compliance with the 3.67% cap set by the deal on Iran's uranium enrichment level, Reuters reported.
