Hamas leader Hamas military leader Abu Ubaida told the Washington Post in September that the Hamas military wing is operating "in harmony with the attitude of the political wing," based in Damascus, Syria.[9] Abu Ubaida, who is a spokesman for the military wing of Hamas, further said that resistance will be stepped up and that all options were open. “We declare that the actions of resistance have gone into a new and advanced stage of co-operation in the field at the highest levels in preparation for more effective attacks against the enemy.”[2] According to the Palestinian Authority and Israeli security officials, Hamas has the capacity to carry out more attacks in the West Bank, particularly drive-by shootings since these require little planning or manpower, but probably lacks the ability to carry out attacks on Israel inside the Green Line due to surveillance activities and the effectiveness of the Israeli West Bank barrier.[9]
