"The trilateral negotiations of military experts within the Astana Russia-Iran-Turkey format are scheduled to take place on August 8-9. There is no 100-percent guarantee that these talks will take place until the final consent of the Turkish side is received," the spokesperson said.
According to the spokesperson, it is not clear so far, who will head the Russian delegation.
"We expect to receive this information," the spokesperson added.
"He [Rogozin] will arrive early in the morning on August 5 and leave in the evening. The aim of the visit is to take part in the inauguration ceremony of Iranian President Hassan Rouhani and maybe a meeting with Iranian Defense Minister Hossein Dehghan. It has not been fully agreed yet," the embassy's representative said.
The presidential election in Iran took place on May 19. Rouhani was reelected for a second term in office by gaining 57 percent of votes with the turnout amounting to 70 percent.
