Spokesman Abbas Araghchi was quoted by the semiofficial ISNA news agency as saying today that American and European leaders and officials were among those invited to the swearing-in of Hasan Rouhani.
Rouhani has pledged to follow a "path of moderation" and promised greater openness over the country's nuclear program, which has placed it at odds with the West.
Araghchi did not elaborate as to which individual leaders would be invited.
Officials in Israel, which the Islamic Republic does not recognise, would presumably not be included.
