The head of the Iranian Atomic Energy Organization (IAEA), Ali Akbar Salehi, said Sunday that Tehran has no choice but to reduce its commitments under the agreement on its nuclear program, the makes "broken promises" of Europeans.

Salehi made the remarks alongside Cornel Feruta, director general of the International Atomic Energy Agency (IAEA), visiting Tehran.

The visit follows the announcement by Iran of the launch of advanced centrifuges to increase its stock of enriched uranium. This initiative represents a new step in the reduction of Iran's nuclear commitments made in 2015 under the Vienna Agreement.

Tehran began in May to withdraw from its obligations, in response to Washington's unilateral withdrawal from the agreement in May 2018 and the inability of the European parties to the text (Germany, France, United Kingdom) to help it bypass sanctions reinstated by the United States.
