Ahmed Qurei
Unable to rule effectively under Arafat, Abbas resigned in September 2003. Ahmed Qurei (Abu Ala) was appointed to replace him. The Israeli government gave up hope for negotiated settlement to the conflict and pursued a unilateral policy of physically separating Israel from Palestinian communities by beginning construction on the Israeli West Bank barrier. Israel claims the barrier is necessary to prevent Palestinian attackers from entering Israeli cities. Palestinians claim the barrier separates Palestinian communities from each other and that the construction plan is a de facto annexation of Palestinian territory.
