Turkish-backed Syrian rebel fighters advance toward jihadist-controlled Idlib province along the Syria-Turkey border on Oct. 6. Turkish forces have deployed in large numbers in the vicinity of Idlib and military action is imminent.
Weeks after Turkish forces started to deploy in large numbers along the border with Syria, adjacent to the province of Idlib, Ankara appears to be on the verge of launching yet another significant military operation into the war-torn country. Unlike Operation Euphrates Shield, which targeted lands occupied by the Islamic State, the upcoming operation into Idlib will be directed toward lands occupied by Syrian rebels. As befitting a convoluted conflict such as Syria, Turkey's advance into Idlib will be assisted by other Syrian rebel groups trained over time by Turkey in neighboring Aleppo province. And according to Turkish President Recep Tayyip Erdogan's latest statements, they will be supported by Russian aviation. Given that Turkey has for years directly supported rebel factions in Idlib in their fight against Russian- and Iranian-backed loyalist forces, the prospect of Turkish forces advancing into Syria under Russian air cover appears jarring at face value.
