Iran nuclear talks underway, expectations low

Iran began talks on Friday with six world powers trying to persuade it to rein in its nuclear program, but there were few expectations of major progress, Western diplomats attending the talks in Istanbul said.

Western countries believe Iran is working to develop a nuclear bomb. Tehran says its nuclear program is peaceful. Friday's talks in Istanbul are a follow-up to talks last month in Geneva, which were the first held in more than a year. (Reuters)
