VIENNA: Talks between US Secretary of State John Kerry, his Iranian counterpart and the EU foreign policy chief towards advancing troubled negotiations on Iran's nuclear drive started on Wednesday, an AFP reporter said.

The discussions in Vienna between Kerry, Mohammad Javad Zarif and Catherine Ashton come six weeks before a November 24 deadline to strike a deal aimed at easing concerns about Iran's atomic programme.
