"Negotiations between Iran and the P5+1 group on a definitive agreement will take place in New York at the end of Bahman," the Iranian month that ends on February 19, IRNA quoted the unnamed source as saying.
The talks will be attended by Iranian Foreign Minister Mohammad Javad Zarif and EU foreign policy chief Catherine Ashton, who represents the so-called P5+1 -- Britain, China, France, Russia, the United States and Germany -- said the source.
He said that the negotiations will focus to draft the comprehensive agreement which will envisage cooperation of the western governments with Iran over the national nuclear program.
The western governments will guarantee to end propaganda campaign against Iranian nuclear program and lift the sanctions they imposed on Iran.
Zarif on Saturday said the talks would resume in February but did not reveal where they would be held.
Previous rounds of talks that led to a landmark interim nuclear deal in November were held in Geneva.
The deal was clinched on November 24, 2013, between Iran and the so-called P5+1.
Under the Geneva deal, the six countries undertook to provide Iran with some sanctions relief in exchange for Iran agreeing to limit certain aspects of its nuclear activities during a six-month period. It was also agreed that no nuclear-related sanctions will be imposed on Iran within the same timeframe.
