An American official says U.S. Secretary of State John Kerry will meet with his Iranian counterpart in Paris on Friday in what will be their second face-to-face encounter this week.

The American official said the meeting will take place at Kerry's hotel in the French capital before he returns to Washington. The pair spent six hours together in Geneva on Wednesday on the eve of a new round of nuclear negotiations among Iran, the five permanent members of the UN Security Council and Germany.

The Paris meeting comes as the negotiators in Geneva grapple to reach a framework accord that would address international concerns about Iran's nuclear program by a March target date.
