Despite the recent coordination between opposition groups in the Military Operations Command (MOC) coalition led by Hayat Tahrir al-Sham (HTS), the future shape of Syria remains uncertain due to historical hostilities and ongoing divisions among the different armed groups throughout the country. ACLED data highlights previous confrontations between these groups since April 2020, when the territorial control of the country was frozen (see maps below). Although Islamic State fighters no longer control territory in Syria, their interactions with key actors — including the Syrian Democratic Forces (QSD) — remain an important dimension of the conflict.
