Nuclear program of Iran
Iranian President Hassan Rouhani inaugurates a series of advanced uranium enrichment centrifuges at the Natanz nuclear facility, revealing that Iran had violated in kind the Joint Comprehensive Plan of Action which mandates the testing and usage of only "first-generation" centrifuges for uranium enrichment, in response to Western sanctions violating the deal. The move comes amid indirect discussions in Vienna between Iran and the United States to revive the deal.
