TEHRAN (Fars News Agency) -- Two International Atomic Energy Agency (IAEA) inspectors are due to arrive in Tehran on Friday to pay visits to Natanz and Isfahan nuclear facilities.

"The two are to inspect the Isfahan UCF Plant and the Natanz Enrichment Facility during their one week sojourn in Iran," an informed source told FNA, adding that the inspections fall within the context of the NPT safeguard agreement.

The visit follows a series of similar inspections to the same facilities, including the last one-week inspection of the Isfahan and Natanz nuclear installations and facilities by two other IAEA inspectors from June 21st to 28th.

Despite frequent allegations by the U.S. and some EU states against Iran's nuclear plans and activities, more than 2000 man/days of IAEA inspections carried out of the different Iranian nuclear facilities and installations have proved Tehran's transparent cooperation with the IAEA.

The recent report by the IAEA Secretary-General Mohammad ElBeradei on June 8th which stressed Iran's full cooperation with the agency substantiates the very same fact.
