IRNA � The second phase of reduced commitment to the Joint Comprehensive Plan of action took effect on Monday with uranium enrichment higher than the %3.67 percent ceiling, the spokesman of Atomic Energy Organization of Iran said on Monday.

"Each phase of the reduction of commitments is defined for a two-month period," said Behrouz Kamalvandi, adding that the %20 enrichment is one of the options for the third phase.

"We waited for two months and then started the second phase yesterday. Of course, the move was after a year-long patience so that the other party should have done its commitments; but they made no proper moves, so according to the order of the president and the Supreme National Security Council, we surpassed the %3.67 limit."
