VIENNA – Iran continues to increase its stockpile of low-enriched uranium far beyond the limits set in a landmark nuclear deal with world powers and to enrich it to a greater purity than permitted, the U.N.’s atomic watchdog agency said Wednesday. The IAEA reported that Iran has also been continuing to enrich uranium to a purity of up to 4.5%, higher than the 3.67% allowed under the deal. Iran has openly announced all violations of the nuclear deal in advance, which have followed the decision by the U.S. to pull out unilaterally in 2018. The deal promises Iran economic incentives in exchange for the curbs on its nuclear program. Before agreeing to the nuclear deal, Iran enriched its uranium up to 20% purity, which is a short technical step away from the weapons-grade level of 90%.
