Battle of Sarrin (June–July 2015)

The Battle of Sarrin (June–July 2015) was a military operation during 2015 in the northeastern Aleppo Governorate, during the Syrian civil war, in which the Kurdish YPG and Free Syrian Army forces captured the town of Sarrin and the surrounding region from the Islamic State (IS). Following nearly two months of a stalled earlier offensive, YPG-led fighters renewed offensive operations on Sarrin on 18 June 2015, followed by a full-fledged operation on 1 July, after ISIL's Kobanî massacre.
