AFP, Friday 16 May 2014

Iran's chief nuclear negotiator reported "no tangible progress" at talks in Vienna with world powers that ended Friday and said differences were "too huge" to start drafting a final accord.

Abbas Araqchi, quoted on state television after three days of discussions, added however that Tehran remained "determined" to continue the talks in coming months.
