Iran has raised the possibility it would stop expanding its stockpile of uranium enriched to a purity of 60 percent — very close to the level needed for a weapon, the U.N.’s nuclear watchdog says.

A report from the United Nations' nuclear watchdog reportedly says Iran further increased its stockpile of uranium enriched.

Iran is moving to stop producing enriched uranium at levels close to what is required for nuclear weapons now that it has stockpiled nearly 32 times the limit set in the 2015 nuclear deal.

Iran has agreed to stop producing uranium enriched close to the level required for nuclear weapons, according to United Nations inspectors.

Iran has offered not to expand its stock of uranium enriched to up to 60% purity, near the roughly 90% of weapons grade, and made preparations to do that, the U.N. nuclear watchdog said in confidential reports to member states on Tuesday.

Iran has taken a preparatory technical step towards curbing its production of highly enriched uranium, the head of the International Atomic Energy Agency (IAEA), Rafael Grossi, said on Tuesday, several days after his talks in Iran.

Iran has defied international demands to rein in its nuclear program and has increased its stockpile of uranium enriched to near weapons-grade levels, according to a confidential report by the United Nations’ nuclear watchdog seen Tuesday by The Associated Press.
