Clashes erupted Sept. 29 between Hayat Tahrir al-Sham (HTS) and the Free Syrian Army (FSA)-affiliated National Liberation Front, backed by Turkey, near the town of Sarmin, east of Idlib province in northwest Syria.
The violence broke out after HTS attempted to expel members of Faylaq al-Sham (Sham Legion), who were present at a military post separating the areas of the Syrian government and the opposition.
