Iran is still complying with the 2015 nuclear deal despite the withdrawal of the US, the UN's nuclear watchdog has said.
A confidential quarterly report, distributed to member states and seen by the Associated Press, reveals the International Atomic Energy Agency has said Iran is continuing to comply with the Joint Comprehensive Plan of Action (JCPOA).
The agency had access to all sites in Iran that it needed to visit, according to the report, and inspectors confirmed Iran had kept within limits of heavy water, and low-enriched uranium stockpiles.
The US decided to pull out of the deal in May, but Germany, Britain, France, Russia and China have reaffirmed their commitment to it in the wake of Donald Trump's decision.
The remaining nations offered economic incentives in exchange for nuclear curbs.
Iran's economy struggled since the US announced its withdrawal, with its currency plummeting.
The deal limits Iran's enrichment and stockpiling material which could be applied to a nuclear weapons programme.
In exchange, Tehran was given widespread relief from international trade, oil, and banking sanctions.
The agency's report, the second it has released since Mr Trump announced the US would pull out and reimpose sanctions, welcomed the cooperation received from Iran.
It added: "Timely and proactive cooperation by Iran in providing such access facilitates implementation of the additional protocol and enhance(s) confidence."

A senior diplomat added: "The production rate (of enriched uranium) is constant. There is no change whatsoever."
In the report in May, the agency had said Iran could do more to cooperate with inspectors.
