Iran said Wednesday the Islamic Republic would hand over documents on its past nuclear activities to the U.N. nuclear watchdog later in the day to allay international suspicions it is planning a bomb. The move would meet a key demand of the International Atomic Energy Agency (IAEA), which had given Tehran an October 31 deadline to clear up suspicions about its nuclear ambitions. Iran has always denied that it is seeking to make nuclear weapons and Tuesday agreed to sign up to tougher IAEA inspections and suspend uranium enrichment as part of a deal hailed as a positive step by President Bush. The IAEA has said its primary current concern is to ensure it has complete information about the origin and history of Iran\'s sophisticated uranium enrichment system. Tehran agreed to the snap inspections and to freeze uranium enrichment Tuesday in an agreement hailed by three visiting European ministers as a promising start to removing doubts about Iran\'s atomic aims. Iran\'s President Mohammad Khatami said Wednesday the protocol would need parliamentary approval. \"It will have to be presented to parliament. It is like all other agreements,\" he told reporters. Under the agreement brokered by the foreign ministers of Britain, France and Germany in Tehran Tuesday, Iran pledged to implement the tougher inspection regime ahead of ratification. It was not immediately clear when a parliament vote would take place. Its outcome is uncertain because although parliament is dominated by pro-Khatami reformists, all legislation must go to hard-line supervisory body the Guardian Council. \"It shows how delicate the agreement is, the proof will be in the implementation,\" said one European diplomat close to Tuesday\'s deal. However, political analysts said Iran\'s reformist government would have never struck the deal without the approval of Supreme Leader Ayatollah Ali Khamenei which meant there should be little resistance from the Guardian Council.
