In a briefing to the UN Security Council, IAEA Director General Yukiya Amano reiterated that "in my regular reports... I have stated that Iran is implementing [its JCPOA] commitments. It is essential that Iran continues to fully implement its commitments. Our inspectors have had access to all the sites and locations in Iran which they need to visit". He went on to underscore that "the implementation in Iran of the Comprehensive Safeguards Agreement, Additional Protocol and additional transparency measures under the JCPOA amounts to the most robust verification system in existence anywhere in the world".
