(CNN) Iran's stockpiles of enriched low-grade uranium have exceeded the 300-kilogram limit set in a landmark 2015 nuclear deal, Foreign Minister Javad Zarif said on Monday according to the state-run IRNA news outlet. The deal limited Iran's uranium enrichment in exchange for an easing of international sanctions. Foreign Ministry Spokesperson Abbas Mousavi said Tehran's latest moves were reversible. Iran had threatened to surpass the maximum permitted amount of enriched uranium in retaliation to crippling US economic sanctions . During talks in Vienna Friday, European countries still party to the deal made a last-ditch effort to persuade Iran to back off from plans to breach the limit.
