The International Atomic Energy Agency said Iran had denied its inspectors access to a nuclear facility in the country.
Earlier this month, the IAEA received a pledge from Iran to cooperate to preserve data from surveillance cameras at the country’s nuclear facilities.
In a report the UN nuclear watchdog sent to its members on Sunday, it was explained that inspectors were not allowed to visit a centrifuge component manufacturing workshop in Karaj, on the outskirts of Tehran. .
IAEA Director General Rafael Grossi expressed concern that Iran was violating its agreement with the agency.
Iranian Ambassador to the IAEA Kazem Gharibabadi tweeted that the report was not accurate. The message indicates that the equipment is not included in the list of items subject to IAEA inspections.
The report notes that inspectors paid a three-day visit to Iran early last week. They were there to maintain IAEA surveillance equipment and replace data storage units in cameras that monitor Iran’s nuclear development activity.
Observers say Tehran is stepping up nuclear development in response to the continued imposition of US sanctions against the country. It also restricts the activities of IAEA inspectors, making it difficult for the UN agency to get a full picture of Iran’s nuclear program.
