Turkey has requested a closed-doors meeting in Iran next week to conceal its stance ahead of the next round of Astana negotiations, Syrian Deputy Foreign Minister Faisal Mekdad told Sputnik on Monday.

The Tehran talks are scheduled for April 18-19, followed by the May 3-4 talks in the Kazakh capital.

"The Turkish government asked the organizers of the meeting not to allow the press, likely so that it did not know the position of the Turkish government," Mekdad said.
