Talks between world powers and Iran have failed to reach an agreement on Tehran's nuclear programme.

EU foreign policy chief Catherine Ashton told a press conference that there had been a lot of "concrete progress but some differences remain".

Baroness Ashton, who co-ordinated talks, said they would resume on 20 November.
