VIENNA (AP) — 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 International Atomic Energy Agency reported in a confidential document distributed to member countries and seen by The Associated Press that Iran as of Nov. 2 had a stockpile of 2,442.9 kilograms (5385.7 pounds) of low-enriched uranium, up from 2,105.4 kilograms (4,641.6 pounds) reported on Aug. 25.

The nuclear deal signed in 2015 with the United States, Germany, France, Britain, China and Russia, known as the Joint Comprehensive Plan of Action, or JCPOA, allows Iran only to keep a stockpile of 202.8 kilograms (447 pounds).

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.
