The nuclear monitoring body made the announcement in its restricted quarterly report on Wednesday.

The report, meanwhile, added that the Islamic Republic has started limiting parts of its nuclear program, in compliance with July's landmark deal with the P5+1 group of countries.

Tehran "has started removing centrifuges and related infrastructure" at both the Natanz and Fordo enrichment facilities, said the IAEA.

Iran and the P5+1 group of countries – the United States, Britain, France, China and Russia plus Germany – clinched a deal, known as the Joint Comprehensive Plan of Action (JCPOA) in the Austrian capital, Vienna, on July 14, PRESS TV reports.

On that same day, a roadmap for “the clarification of past and present outstanding issues” regarding Iran’s nuclear program was signed by the agency’s Director General Yukiya Amano and Head of Atomic Energy Organization of Iran Ali Akbar Salehi in Vienna.

Under the JCPOA, limits will be put on Iran’s nuclear activities in exchange for, among other things, the removal of all nuclear-related economic and financial bans against the Islamic Republic.

Tehran has repeatedly said it would abide by its commitments under the JCPOA warning the other countries of any non-compliance with their obligations.
