“The third stage of Iran (to reduce obligations under the nuclear deal. - RT ) is under the supervision of the IAEA and it is reversible,” the Iranian leader’s website said in a statement.

In addition, the Iranian leader at a government meeting said that Tehran would further reduce its nuclear deal obligations if necessary.

Earlier, Iran decided to select material from enriched and depleted uranium. Such a step was taken in connection with the refusal to fulfill a number of obligations under a nuclear deal.
