Iran is once again breaching the restrictions of its 2015 nuclear deal with major world powers.
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.
For more on this and other news around the world, let's turn to our Kim Da-mi.
Da-mi, tell us more about this latest violation?
Connyoung, Iran has committed yet another breach...this time by enriching uranium with advanced centrifuges.
This is according to a report by the International Atomic Energy Agency on Thursday.
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.
The lines comprise small cascades of up to 20 centrifuges.
Based on the report, Iran is still installing two previous announced 164-machine cascades of the IR-4 and IR-2m models.
These are the two cascades that were removed under the deal and that lead to the world power lifting international sanctions against Iran.
The nuclear deal permits Iran to accumulate enriched uranium with just over 5-thousand of its first-generation IR-1 centrifuges.
Iran is also allowed to use small numbers of more advanced models for research...WITHOUT producing enriched uranium.
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.
