The Northwestern Syria campaign (October 2017 – February 2018) was a large-scale military operation that initially started with an offensive conducted by ISIL forces on areas controlled by Tahrir al-Sham (HTS) in the northern Hama Governorate. Subsequently, the Syrian Armed Forces launched their own offensive against HTS and other rebel groups in the area. The campaign took place at the intersection of the provinces of Hama, Idlib and Aleppo.
