The sources in Northern Hama reported that a Turkish delegation, accompanied by a number of military vehicles, entered Idlib province and visited four points in Khan Sheikhoun region in Southern Idlib and in the towns of Morek, Lahaya, Kafr Zita and al-Sayad in Northern Hama.
The sources said that the Turkish delegation's visit was aimed at setting up the eighth de-escalation zone monitoring post in Northwestern Syria.
Other sources said that the Turkish army is to set up the eighth monitoring post in al-Zaytouniyeh in Jabal al-Turkaman region in Northern Lattakia.
In the meantime, the Turkey's state-run Anadolu said Iran and Russia have established eight Monitoring Posts in Idlib province, but not in the regions that are under monitor by the Turkish forces.
Tehran and Moscow have not yet made any comment on the report.
The Iranian, Russian and Turkish presidents, in a meeting in Ankara on Wednesday, underlined their frim intention to expand their mutual cooperation to access a sustainable ceasefire among warring sides in Syria.
In a relevant development on Friday, the Russian and Turkish military delegations agreed to the preliminary terms regarding the strategic town of Jisr al-Shughour in Southwestern Idlib province and nearby al-Ghaab Plain in Northeastern Lattakia.
Turkey gave the green light to the Russian military and Syrian Army to conduct an offensive to retake Jisr al-Shughour and nearby al-Ghaab Plain, which would give the latter access to another Turkish border-point.
The agreement would be a major plus for the Russian military and Syrian Army, as the terrorists often fire missiles from Jisr al-Shughour into the coastal province of Lattakia.
