Mohammad Eslami, who leads the Atomic Energy Organization of Iran, said on Wednesday that the country is still committed to an understanding reached with the IAEA earlier this year that outlines the way the country should comply with the agency’s general directives and rules, including the Non-Proliferation Treaty (NPT) and its safeguards agreements.

“The Islamic Republic of Iran does not accept any nuclear activity that could disrupt ties with the IAEA,” he told reporters on the sidelines of a Cabinet meeting in Tehran.

He said, however, that Iran will continue to observe a parliament law ratified some four years ago which outlines how it should comply with the terms of a 2015 nuclear agreement with world powers.

The comments came after IAEA Director General Rafael Grossi claimed earlier this week that Iran has yet to clarify some ambiguities surrounding its nuclear program.

Eslami denied there are any ambiguities and said that nuclear activity in Iran is under constant inspection and monitoring by some 120 inspectors approved by the IAEA.
