Iran has warned the US against violating the nuclear deal between Tehran and the P5+1 group of countries, also known as the JCPOA.
Zarif was speaking to reporters in the city of Isfahan. He also said Iranian scientists have made operational the most advanced centrifuges over the past two months. Zarif added that these centrifuges are able to enrich uranium 20 times more than the previous ones.
International bodies including the IAEA have time and again announced that Tehran has fully complied with its commitments under the nuclear deal.
