Iran announced that it would begin using advanced centrifuges to enrich uranium in violation of the Joint Comprehensive Plan of Action (JCPOA). The JCPOA capped Iran at approximately 6,000 first-generation IR-1 centrifuges with a small number of more advanced models allowed for research purposes. Atomic Energy Organization of Iran (AEOI) spokesman Behrouz Kamalvandi said that Iran would lift limitations on "research and development imposed by the deal," including the implementation of 20 IR-6 centrifuges as well as tests of the IR-8 model. Iran says that these steps are reversible if European partners can restore its access to international trade, setting another 60-day deadline for Europe before it will further reduce JCPOA commitments.
