During the last few months an increasing number of "brigades" have appeared in Judea and Samaria, military-terrorist networks calling themselves al-Aqsa Martyrs' Brigades (AAMB). Although the AAMB are usually affiliated with Fatah, today it is the generic name for armed squads of Palestinian terrorists, most of which operate independently and have neither a central leadership nor an established structural hierarchy. Fatah and the PA are ambivalent, publicly claiming to promote the so-called "unarmed popular resistance," while the AAMB publicly promote armed "resistance" [terrorist attacks] and a "military option”.
