By the beginning of 2015, the group had suffered 200 killed and over 400 wounded since its establishment.[5] The group supported the Syrian Army in its effort to reopen the main supply line to Aleppo in late 2015.[12]
In June 2017, Liwa al-Quds launched a recruitment campaign in Homs Governorate, where it aimed at enlisting young Palestinian refugees.[13][14]
In May 2018 Liwa al-Quds was fighting against the ISIL pocket in the desert of Deir ez-Zor Governorate as a part of joint operation with the NDF and SAA forces. Liwa al-Quds captured village of Faydat Umm Muwaynah.[15]
In July 2018, Samer Rafe, a prominent commander of the militia, was arrested in Latakia after a firefight with government forces. He had previously been arrested on charges of robbery in Aleppo, confessed to the charges, and served a prison term of one year before being released.[16]
In the first half of 2019, Liwa al-Quds suffered heavy casualties on multiple fronts, most notably during Operation Dawn of Idlib.[17]
Compostition
The brigade has both Syrian Palestinian as well as native Syrian members.[11] The brigade has close connections to both Iran and Russia, and is supplied as well as trained by the Russian Armed Forces.[17][18] Its fighters refer to themselves as "Syrian Arab Army Fedayeen", showcasing their loyalty to the Syrian military.[17] Before the government victory in the Battle of Aleppo, the brigade consisted of three main battalions, which are: Lions of al-Quds Battalion, which operated in al-Nayrab camp and its surrounding as well as in southern and eastern countryside of Aleppo; the Deterrence Battalion, which operated in the north Aleppo countryside south of the villages of Nubl and Al-Zahraa; and the Lions of al-Shahba' Battalion, which operated inside Aleppo city.
By 2018, the group had started recruiting former Syrian rebels that agreed to join pro-government military units as part of reconciliation deals with the Syrian government. More than 150 former Free Syrian Army fighters had joined Liwa al-Quds by 2019. They received military training and supervision from Russian officers during the first quarter of 2019.[19] In fall 2019, Liwa al-Quds became part of the Syrian Army's 5th Assault Corps as autonomous brigade.[20][21]
