Iran and three world powers have been handed a draft agreement aimed at reducing international concerns over Tehran's nuclear program. The International Atomic Energy Agency, which proposed the plan after talks in Vienna, wants an answer by Oct. 23. Details are yet to be confirmed, but the plan is believed to involve Iran exporting uranium to be enriched in France and Russia. Iran's chief negotiator has not commented on the uranium export plan. The negotiations have involved the UN, Iran, France, Russia and the US. IAEA director Mohamed ElBaradei told reporters in Vienna that he was feeling "optimistic" after the talks, which he said had been "very constructive." (BBC)
