Iran is voluntarily cooperating with the U.N. nuclear watchdog to show to the world that U.S. allegations on Tehran`s secret programs to develop nuclear weapons are totally baseless and sheer lies, said a top security official here Monday. Talking to reporters after a Majlis session Monday, Secretary of Iran`s Supreme National Security Council Hassan Rowhani said that Iran`s cooperation with IAEA was not because of Europe but is aimed at proving that all US accusations against the Islamic Republic were "baseless and unfounded."

Asked on the western media reports that Iran did not accept the latest proposals of the E.U. big trio (Britain, France and Germany) on its nuclear case and that the case should now be referred to the UN Security Council, Rowhani said that the word "Security Council" was not threatening and that it would not exert any pressure on the Islamic Republic. "All activities of Iran have been transparent and legal," said the official adding "therefore, taking our case to the UN Security Council would be useless for those who are after it."

"What the council is going to do now that Iran is to continue its cooperation within the framework of the international regulations," Rowhani said. He added that Tehran wanted its nuclear case closed on the basis of legal documents in order to prove to the world that its nuclear programs were only for peaceful purposes.

As for the latest report of the IAEA inspectors on Iran`s nuclear case, Rowhani said that based on what has been announced by the UN nuclear watchdog, only two more issues have been left to be explained which were related to the P2s and contamination of Iran`s nuclear equipment. The two issues are related to "third countries", Rowhani said without naming any certain state.

"It is possible that part of Iran`s nuclear case has not been completed yet because a third state has not extended proper cooperation with the IAEA," Rowhani said. He added "that is the problem of the IAEA and the third country and it has nothing to do with the Islamic Republic." The Iranian top nuclear negotiator added "As far as the Islamic Republic is concerned, it has completed what it was to do regarding its nuclear case," so it can be said that Tehran`s measures has been completed in this regard.

As for Tehran`s measures to prevent Washington from influencing Iran`s nuclear case, Rowhani said that If there has not been such moves by the US, Iran`s nuclear case could have been finalized so far. The problem is that the US and some of its supporters are against Iran and the country should move its case ahead despite all obstacles being created by them, Rowhani added. However, he added, Iran has succeeded in making many progress regarding its nuclear case despite the said problems and despite the fact that the US has been demanding in all meetings that Iran`s case should be referred to the UN Security Council.

Asked what would Iran do in the event its nuclear case is sent to the Security Council, the top Iranian security official said that such a move, if taken, would be considered a politically-motivated one.
