A fresh round of negotiations has got underway to try and resolve the long-standing dispute over Iran’s nuclear programme.
Representatives from six world powers have been meeting with Tehran’s nuclear negotiator in the Turkish city of Istanbul.
The atmosphere at the opening session has been described as “completely different” from that of previous gatherings.
One diplomat said negotiator Saeed Jalili had not come forward with the same preconditions as before.
He also suggested that Iran was indicating a willingness to engage, possibly paving the way for a second meeting.
“What we are here to do is to find ways in which we can build confidence between us and ways in which we can demonstrate that Iran is moving away from a nuclear weapons programme,” said Catherine Ashton, EU foreign policy chief.
The West accuses Iran of seeking to develop a nuclear weapons capability, while Tehran insists that its programme is peaceful.
The talks in Istanbul are the first between Iran and the world powers in 15 months.
Last time they met, the two sides could not even agree on an agenda.
