A report by the UN nuclear watchdog said it was difficult to determine if Iran had disclosed the full extent of its nuclear programme last year, a diplomat told reporters today.
The report by the International Atomic Energy Agency (IAEA) said a combination of highly-enriched and low-enriched uranium had been found at two sites in Iran and that this had not yet been fully explained.
"Until this matter is satisfactorily resolved, it will be very difficult for the agency to confirm that there has not been any undeclared nuclear material or activities," the diplomat, who follows the IAEA closely, quoted the report as saying.
The report also said Iran's nuclear disclosure last October did not include designs for advanced P2 centrifuges because of time pressures. The agency said this was "difficult to comprehend", the diplomat said.
