Yukiya Amano, the Head of the Global Nuclear Watchdog the (IAEA), has paid a visit to Iran’s Parchin Military site in Iran.
Mr Amano arrived Iran on Sunday. His visit was seen by western diplomats as key to the implementation of the deal with world powers over Iran’s nuclear programme.
Under the new deal, inspectors from the IAEA will continuously monitor Iran’s declared nuclear sites and verify that no fissile material is moved covertly to a secret location for bomb.
Iran has also agreed to allow inspectors to access any site they deem suspicious.
International inspectors had previously had limited access to the complex.
In a 2006 report, the IAEA said its inspectors “did not observe any unusual activities in the buildings visited, and the results of the analysis of environmental samples did not indicate the presence of nuclear material”.
But concerns have persisted. In late 2011, the IAEA said it observed extensive landscaping, demolition and new construction at the site.
In February 2012, inspectors were turned away from the site.
The deal agreed in July entailed Iran agreeing to limit its sensitive nuclear activities in return for an end to crippling international sanctions.
US said the deal would prevent Iran from acquiring a nuclear weapon. US Republicans had opposed the deal but an attempt to derail it was been blocked by Democrats in the Senate earlier this month.
