Yukiya Amano of the International Atomic Energy Agency said today that Tehran has met a deadline and taken "excess centrifuges and infrastructure" from what used to be the Fordo uranium enrichment facility.
The main focus of the nuclear deal is limiting Iran's uranium-enrichment capacities out of fear Tehran could spin uranium in its centrifuges all the way to levels used for the core of a nuclear weapon.
Iran says it is not interested in such arms.
