During the 1975-77 phase of the Lebanese Civil War , the al-Murabitoun militia forces were heavily committed in several battles and suffered considerable casualties , especially at the Battle of the Hotels in October 1975 where they engaged Christian Kataeb Regulatory Forces and Tigers Militia fighters , and later at the ' Spring Offensive ' held against East Beirut and Mount Lebanon in March 1976 . They also took part that same year in the violent ( and controversial ) sieges of the Christian towns of Es-Saadiyat , Damour , and Jiyeh in the Iqlim al-Kharrub , on the side of PLO and Palestine Liberation Army ( PLA ) units to avenge the earlier Tel al-Zaatar massacre by the Lebanese Front militias
