IAEA Director General Yukiya Amano has doubts about success at the next round of talks on the nuclear program with Iran, Interfax-Azerbaijan reports.
Negotiations will be held in Vienna in Friday.
The previous talks were held in early June. Head of the IAEA inspection group Herman Hakerts said that no agreements were reached on allowing inspection of the Parchin nuclear facility, a complex believed to be used for development of nuclear weapons.
The US, Israel and a set of other Western states accuse Iran of developing nuclear arms on the background of peaceful atom. Tehran denies all accusations and insists that the nuclear program is to fulfill demands for electricity.
