For your information:
The Khalid ibn al-Walid Army (Arabic: جيش خالد بن الوليد Jaysh Khalid ibn al-Waleed) is an armed Salafi jihadist group active in southern Syria. It was formed by a merger of the Yarmouk Martyrs Brigade, the Islamic Muthanna Movement, and the Army of Jihad, all affiliated with the Islamic State of Iraq and the Levant, on 21 May 2016. The faction controls a strip of territory southeast of the Golan Heights, and is in conflict with other forces of the Syrian rebels.
The Khalid ibn al-Walid Army enforces a strict form of Sharia. In the small pocket the group controls, its fighters forced women to wear niqabs and men to wear loose trousers and to grow long hair and beards. Since 2016, the group has executed more than 20 people, mostly in the town of Shajara by beheading. The group has also locked smokers in cages and amputated people on allegations of theft.
