Iran is once again breaching the restrictions of its 2015 nuclear deal with major world powers. <br />This seems to be in response to the crushing U.S. sanctions imposed on Tehran since President Trump withdrew Washington from the agreement in May last year.<br />For more on this and other news around the world, let's turn to our Kim Da-mi.<br />Da-mi, tell us more about this latest violation? <br /><br /> Connyoung, Iran has committed yet another breach...this time by enriching uranium with advanced centrifuges. <br /> This is according to a report by the International Atomic Energy Agency on Thursday. <br />On September 25th, two days ago, the agency verified that all of the centrifuge cascades already installed in R&D lines 2 and 3 were accumulating,... OR had been prepared to pile up enriched uranium. <br />The lines comprise small cascades of up to 20 centrifuges. <br /> Based on the report, Iran is still installing two previous announced 164-machine cascades of the IR-4 and IR-2m models. <br />These are the two cascades that were removed under the deal and that lead to the world power lifting international sanctions against Iran. <br />The nuclear deal permits Iran to accumulate enriched uranium with just over 5-thousand of its first-generation IR-1 centrifuges. <br />Iran is also allowed to use small numbers of more advanced models for research...WITHOUT producing enriched uranium. <br />In a letter to the agency on September 25th, Iran said that it's only reconfiguring its enrichment set-up to add clusters of centrifuges. <br />
