The Battle of Ras al-Ayn (8 November 2012 – 20 July 2013) was a series of armed clashes for control of the town of Ras al-Ayn (Kurdish: Serê Kaniyê) during the Syrian Civil War, mainly between the Kurdish-majority People's Protection Units (YPG) and an alliance of Syrian rebel groups (including the al-Nusra Front and the Free Syrian Army), 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.
