A stalemate that had been in place for four years finally ended in July 2016, when Syrian government troops closed the rebels' last supply line into Aleppo with the support of Russian airstrikes. In response, rebel forces launched unsuccessful counteroffensives in September and October that failed to break the siege; in November, government forces embarked on a decisive campaign that resulted in the recapture of all of Aleppo by December 2016. The Syrian government victory is widely seen as a turning point in Syria's civil war.

The Battle of Ras al-Ayn was a series of armed clashes for control of the town of Ras al-Ayn during the Syrian Civil War, mainly between the Kurdish-majority People's Protection Units (YPG) and an alliance with Syrian rebel groups, with the occasional involvement of the Syrian Armed Forces. As result of the battle's first phase, the Syrian Army was expelled from the city by Syrian rebels, whereupon the latter attacked the YPG-affiliated fighters in Ras al-Ayn. In the following months, the city was effectively divided into rebel-held and YPG-held areas, with intermittent fighting resulting in the gradual expansion of the YPG's territory in the city and its surroundings. Islamist and jihadist factions soon became dominant among the rebels in the region, further contributing to tensions with the secular-leftist YPG. In July 2013, the battle's final phase erupted and ended when an alliance of YPG-led troops completely expelled the rebels from Ras al-Ayn.
