According to YNet News, Hamas is arming for a showdown with Fatah in the West Bank:
Hamas officials told Ynet that hundreds of automatic rifles have been smuggled into the West Bank to bolster the group’s military presence there….
Efforts of rearmament are being overseen from Damascus by Hamas politburo chief Khaled Mashaal who believes the group should be prepared for “the moment of truth” should President Abbas dare to dissolve parliament and declare new elections.
