VIENNA - The governing board of the International Atomic Energy Agency (IAEA) approved on Thursday a resolution, expressing "serious concern" on Iran's disputed nuclear program.

The IAEA resolution urged Iran to comply fully with all of its obligations under the relevant Resolutions of the UN Security Council "without delay," including the application of the modified Code 3.1 and the implementation and prompt entry into force of the Additional Protocol.

The resolution said that Iran "continues to defy the requirements and obligations" contained in the relevant IAEA Board of Governors and UN Security Council Resolutions, including the continuing and expanding uranium enrichment activities, in particular at the Fordow Fuel Enrichment Plant.

It said as Iran is not providing the necessary cooperation, the IAEA is unable to provide evidence that all nuclear material in Iran is in peaceful activities.

The country is requested to provide the access for the IAEA to relevant sites.

The resolution can only complicate the issue by politicizing it, said Iran's envoy to the IAEA Ali Asghar Soltanieh.

The conclusion reached in the resolution has been based on information from westen intelligence agencies, which the envoy said was biased and contains distortion of facts.
