The Iranian foreign minister, Mohammad Javad Zarif has told the visiting EU foreign policy chief, Catherine Ashton, that a nuclear deal could come in the next four months.

Baroness Ashton told the BBC's Lyse Doucet that there was "no guarantee" her talks would lead to a comprehensive agreement, and that she took nothing for granted.
