Opinion is divided at the International Atomic Energy Agency over how to deal with Iran after it insisted it will press on with its nuclear programme. IAEA chief Mohammed el Baradei has called for transparency from Tehran but also for more unity from the UN watchdog’s members:“With regard to Iran I think we regrettably are going through a period of confrontation and political brinkmanship. I very much hope that this week all the parties should work together to create the necessary conditions to get back to the negotiating table. The IAEA has gathered at its Vienna headquarters to decide if Tehran should be referred to the United Nations Security Council for possible sanctions. Outside demonstrators demanded Iran face penalties, echoing a fear held by Washington that the Islamic nation intends to make a nuclear bomb.
