The five major nuclear-armed powers said on Friday the Non-Proliferation Treaty was under threat and cited Iran's uranium enrichment campaign in a rare joint call for action to shore up the NPT. Iran says it wants only electricity from enrichment, which can also produce atom bomb fuel if the process is adjusted.
Iran has slowed the installation of centrifuge machines that enrich uranium for its controversial nuclear programme, the director of the International Atomic Energy Agency said on Monday. Western powers have condemned Tehran's expansion of enrichment work in defiance of United Nations demands.
