Iran is accelerating its nuclear program by stockpiling enriched uranium — the material needed to create atomic bombs — in violation of U.N. Security Council resolutions.

A confidential report this week by the U.N.’s nuclear watchdog agency said Iran‘s stockpile has reached a level 22 times above the limit set by the 2015 nuclear accord between Tehran and world powers.

The findings by the International Atomic Energy Agency suggest that Iran has advanced the program dramatically since 2018, when then-President Donald Trump pulled the United States out of the accord on grounds that it had failed to curtail Tehran‘s funding of terrorist proxy groups like Hamas and Hezbollah.

The IAEA’s confidential report, which was reviewed and first publicized Wednesday by Agence France-Presse, said Iran‘s total enriched uranium stockpile was estimated at nearly 9,900 pounds as of Oct. 28, up by more than 1,500 pounds from August.

The limit in the 2015 accord was set at roughly 500 pounds.
