A new military policy is in force in Binyamin, Judea, and Samaria: More army vehicles will be on the roads, especially during heavy-traffic hours. In addition, the IDF announced that the entrances and exits to PA cities - except Kalkiliyeh and Jericho - will be \"encircled\" as of today, and Arab residents will be permitted to travel the roads only in humanitarian cases. IDF leaders with whom Prime Minister Barak met on Friday told him that the \"low-closure policy\" that had been in force since the beginning of the current war has failed and \"has not prevented even one terrorist attack.\" Even the dirt roads that the Arabs had used to bypass closed roads until now will not be allowed to be used.
