Iran, world powers begin new round of nuclear talks
After three months of broad discussions between Iran and the United States, France, Russia, Britain, China and Germany, the sides plan during their May 14-16 meeting in the Austrian capital to start drafting the text of a final accord that could put an end to years of hostility and mistrust.
Wide differences must still be overcome, especially regarding the size of Iran's uranium enrichment programme, and a successful outcome is far from guaranteed.
Iran denies Western allegations that it has been seeking to develop the capability to make atomic bombs, saying its nuclear programme is a peaceful energy project.
