Iran earlier breached the 2015 nuclear pact’s limit on the purity to which it can enrich uranium to go up to 4.5 percent but enrichment at 20 percent at its Fordow facility is just one technical jump away from weapons-grade levels of 90 percent.
The move is the latest of several recent announcements by Iran to the International Atomic Energy Agency that it plans to further breach the deal, which it started violating in 2019 in retaliation for Washington's withdrawal from the agreement.
