Iran and three world powers have been handed a draft proposal by UN nuclear monitors on Iran's uranium enrichment. Tehran will have until Friday to give its approval of the deal put forward by the International Atomic Energy Agency (IAEA) director Mohamed ElBaradei. Mr. ElBaradei told newsmen in Vienna that he had circulated a draft agreement that in his judgment reflected a balanced approach to how to move forward. He gave no further details on the agreement. The talks in Vienna, involving Iran, France, Russia and the US, had focused on Iran exporting its uranium to other countries to be enriched. Debate stalled yesterday when Iran refused to curb enrichment. Exporting uranium has been seen as a way for Iran to get the fuel it needs, while giving guarantees to the West that it will not be used for nuclear weapons.
