The U.N. nuclear agency says Iran has started cutting back on nuclear programs, which could have been re-engineered into making weapons, in line with a deal between six world powers.

The assessment was in a report presented Wednesday by the U.N.’s International Atomic Energy Agency to members of the U.N. Security Council and a restricted number of other nations.

Implementation day for the July 14 nuclear deal was Oct. 18. Since then, the report shows that Iran has reduced the number of centrifuges it uses to enrich uranium, a potential pathway to nuclear arms.

The report said 11,308 centrifuges were standing at Iran’s main enrichment center as of Nov. 15. That’s more than 300 fewer than before the implementation day. It also noted reductions at a smaller facility.
