Iranian officials and the UN's nuclear watchdog ended four days of talks here aimed at resolving questions related to the Islamic Republic's nuclear program, state media reported. The conclusion of the talks comes as the United States, Russia, China, Britain, France and Germany meet in London on Friday to try to coordinate strategy toward Iran's disputed nuclear activities. A Saudi Arabian official, meanwhile, said Arab states in the Persian Gulf had proposed to Teheran that they set up a consortium to provide Iran with enriched uranium as way to defuse the nuclear fight. The Iranian side expressed satisfaction with the UN discussions, which focused on P-1 and P-2 centrifuges, which are used to enrich uranium, said a report on the Web site of Iran's state broadcasting company. The talks, which began Monday and ended Thursday, were the third round between the two sides to discuss the machines.
