The Descendants of Saladin Brigade participated in the offensive to capture the city of al-Bab and the town of Qabasin as part of Operation Euphrates Shield in late 2016 and early 2017. As part of its participation, the group requested Turkey to allow the flag of Kurdistan to be raised in Qabasin.[21] On 3 April 2017, Ahrar al-Sham reportedly attacked the group in Qabasin and captured more than 8 of their fighters, including a commander. Hours later, the prisoners were released after negotiations, although tensions between the two groups remain.[2]
