Turkish President Recep Tayyip Erdoğan will visit Iran on September 7 and attend the Syria summit with his Iranian and Russian counterparts.

The summit is being held at a time when the Syrian regime is preparing for an operation against Idlib, where the Ankara-backed gangs are.

The Idlib region had been appointed a “no-clash” zone in the Astana negotiations led by Russia, Turkey and Iran.

Turkish Foreign Minister Mevlut Çavuşoğlu had argued that a military solution would be “disastrous” during a visit to Moscow last week. Russia on the other hand had demanded a separation between the “moderate opposition” and others. The region is mostly under control of gang groups under Tahrir Al Sham, formerly known as Al Nusra. Turkey is in direct communication with the gang groups in Idlib.

The most recent meeting between the presidents of Russia, Iran and Turkey about Syria had been held in April, and in November in Sochi before that.

According to Turkish news television NTV, the summit will be held in Tabriz in Northern Iran on September 7.

Erdoğan had announced by late July that they wanted to organize a summit between Moscow, Paris and Berlin on September 7, but Paris and Berlin had not responded.
