Iran is fulfilling its commitments under the nuclear deal with world powers, the head of the International Atomic Energy Agency said on Monday. “The IAEA can state that such nuclear-related commitments are being implemented,” the organization’s director-general, Yukiya Amano, told reporters in Abu Dhabi after a trip to Iran on Sunday. “Regarding the activities by our inspectors, they are discharging their responsibility without problem,” Reuters quoted Amano as saying.
