ALMATY, Kazakhstan (AP) - The EU's foreign policy chief says that nuclear talks between Iran and six world powers have failed to reach an agreement.
Catherine Ashton said Saturday that the talks revealed that "the two sides remain far apart on substance."
The six insist Iran cut back on its highest grade uranium enrichment production and stockpile, fearing Tehran will divert it from making nuclear fuel to form the material used in the core of nuclear warhead.
Iran insists it has a right to enrich but says it has no interest to use the technology to make weapons. It wants more sanctions relief than the six are offering for any concessions on its part.
