Iran says it intends to start enriching uranium to 20% at its Fordow nuclear facility, exceeding regulations set by the 2015 Joint Comprehensive Plan of Action known as the Iran nuclear deal, as first reported by Reuters. Iran has previously suggested this increase could be a possibility.
The nuclear deal includes regulations that Iran cannot enrich uranium past 3.67% and that it specifically cannot conduct any enrichment at Fordow, which is located beneath a mountain near the city of Qom.
