DUBAI (Reuters) - Iran has made 55 kg of uranium enriched to up to 20% - the point at which it is highly enriched - indicating quicker production the 10 kg a month rate required by an Iranian law that created the process in January, Iranian authorities said on Wednesday.
The disclosure comes a day after Tehran and Washington held what they described as "constructive" indirect talks in Vienna on Tuesday aimed at finding ways to revive a 2015 nuclear deal between Iran and world powers.
Iran's hardline parliament passed a law last year that obliges the government to harden its nuclear stance, partly in reaction to former President Donald Trump's withdrawal from the nuclear deal in 2018.
Trump's withdrawal prompted Iran to steadily overstep the accord's limits on its nuclear programme designed to make it harder to develop an atomic bomb - an ambition Tehran denies.
The law required Iran to start enriching to 20% and stipulated that at least 120 kg (265 pounds) of uranium refined to that level be made each year, which amounts to 10 kg a month.
