Technical expert teams of Iran and six world powers (the five UN Security Council permanent members plus Germany) resumed nuclear negotiations in Vienna's Cobourg Hotel on Tuesday night, IRNA reported.
The Iranian team is led by Hamid Baiedinezhad, managing director of Iranian Foreign Ministry's Political and International Affairs Office and the Sextet team is headed by the special assistant of Catherine Ashton, Stephan Clement.
