Iran nuclear talks end, another round set: Tehran

ALMATY, Kazakhstan (CBSNews.com) -  A Western official says the latest round of talks between world powers and Iran over Tehran's nuclear program has ended.

It was not immediately clear what, if anything, was resolved in during the two days of negotiations that ended Wednesday.

But, according to Reuters, Iran's Fars news agency is reporting that Tehran and the world powers agreed to hold another meeting in Almaty after first holding "expert-level" talks in Istanbul.

Iranian state TV reported that technical experts for each side would be involved in the Istanbul sessions.

Reuters cites Russia's ITAR-Tass news agency as saying those negotiations would be held in mid-March.

And Russian Deputy Foreign Minister Sergei Ryabkov was quoted by Russian news agency Interfax as calling the just-finished talks "useful," according to Reuters.

Iran's top negotiator, Saeed Jalili, and EU foreign policy chief Catherine Ashton were expected to talk to reporters later on Wednesday.

The Western official spoke on condition of anonymity because he was not authorized to brief the media.
