VIENNA, July 18. /ITAR-TASS/. Iran and a group of six nations have failed to succeed in finding a solution on the heavy water reactor in Arak and a nuclear facility in Fordo, Russian Deputy Foreign Minister Sergei Ryabkov said on Friday.

"The inability to resolve the problem means that the P5+1 group and Iran do not have a common approach to what a new and modified reactor in Arak should look like or whether it is going to be altered at all. There are various schemes. Approximately the same can be said about the facility in Fordo,” Ryabkov stressed.
