The sources said that the Turkish army convoy, consisting of tens of heavy and personnel-carrier vehicles has entered Idlib through the village of Kafr Lousin at the border with Syria.
They added that the convoy has been deployed in the village of al-Sarman near the town of Ma'ar al-Na'aman in Southern Idlib in line with the Turkish plan to set up the sixth point to monitor implementation of the de-escalation agreement in Idlib province.
Meantime, a Turkish delegation on Wednesday visited several points in Southern Idlib.
The Turkish forces have so far been deployed in five regions, including Tal al-Touqan and Salouy, respectively in the Eastern and Northern Idlib province, and Mount Simon and Mount Aqil in Western Aleppo and Tal Issa in Southern Aleppo.
Dissident-affiliated websites had reported last week that the Turkish army has deployed in the regions to set up monitoring posts in the de-escalation zone after reaching an agreement with Al-Nusra Front (Tahrir al-Sham Hay'at or the Levant Liberation Board).
