Secretary of State John Kerry made history after holding one-on-one nuclear talks with his Iranian counterpart, Foreign Minister Mohammad Javad Zarif, on the sidelines of United Nations General Assembly meet.
Kerry, along with fellow diplomats, met briefly on Thursday with Zarif, marking the highest-level meeting between the two countries since the Iranian revolution of 1979.
According to Fox News, EU foreign policy chief Catherine Ashton later described the talks as 'substantial' and said they had set the stage for a new round of negotiations over Iran's nuclear programme in Geneva.
Speaking to reporters later, Kerry warned there was still 'a lot of work to be done', but added he welcomed the 'change in tone'.
Zarif added that he was 'satisfied with this first step'.
The diplomats met on the sidelines of the U.N. General Assembly in New York, amid mixed signals about how serious Iran was about coming back to the negotiating table over its nuclear programme, the report added.
