Ashton on Iran nuclear deal: 'I take nothing for granted'
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.
World powers want Iran to scale back its nuclear work to ensure it cannot assemble a nuclear weapon.
