Shortly after the beginning of the “Syrian Revolution” in March 2011, hundreds of rebel factions, including some local factions, some were backed by foreign countries and some others were based on religious ideology, were formed throughout Syria. After these factions had controlled eastern Ghouta, eastern Qalmoun and Rif Dimashq and the number of their fighters, including fighter from east Homs countryside and Deir Ezzor, had increased in these areas, Colonel “Bakur al-Salim” formed “Quwat al-Sitin” faction (the Sixtieth Forces) with its headquarter being in al-Hammad region near the Syria-Jordan border, near al-Hadalat area.
