There is still a very significant gap to close in nuclear negotiations betweenIran and the west, the British foreign secretary has said, with high-level talks set to resume over the weekend after consultations in national capitals.
Philip Hammondwas speaking as he left Vienna after four hours of talks with his American, European and Iranian counterparts.
The final round of talks over Irans nuclear programme began on Tuesday, looking to reach a deal under which Tehran would curb its nuclear work in exchange for a lifting of economically crippling sanctions.
The direction of the negotiations was in some confusion on Friday after Iranian officials announced that their foreign minister, Mohammad Javad Zarif, would be flying to Tehran for consultations, then said he would stay.
