Iran nuclear talks in Moscow end 'without breakthrough'

The latest round of talks on Iran's nuclear programme has ended with no clear breakthrough, officials say.

EU foreign policy chief Catherine Ashton said "significant gaps" remained after "tough and frank" exchanges in the talks, in Russia's capital Moscow.

Chief Iranian negotiator Saeed Jalili described the two days of negotiations as "serious", but reiterated enriching uranium was Iran's inalienable right.
