"A group of senior Fatah officials from the West Bank recently began promoting an initiative aimed at persuading Palestinian Authority Chairman Mahmoud Abbas to remove his national security adviser and associate, Mohammed Dahlan. Jailed former commander of Fatah's Tanzim force, Marwan Barghouti, is among those urging the change. The officials, all belonging to Fatah's Revolutionary Council, are demanding Dahlan's removal due to what they perceive as his failure to engage Hamas militarily in the Gaza Strip and prevent the organization from ousting Fatah from power there."
